notice: even though methanol was used, I made sure it was completely evaporated (it evaporates very easily) before consuming. This alcohol is ideal to use in psilo extractions, if readily available. technically, it's not methanol that's toxic; it's not what would make you blind or kill you. it's the formaldehyde that methanol is converted into when it reaches the liver after drinking it that is poisonous. Handling methanol is not as big a concern. "Nothing is true, everything is permitted." ~ hassan i sabbah "Experiments are the only means of attaining knowledge at our disposal.

Thanks for the info on methanol, I may buy some and try it next. I was thinking ethanol only because I can drink it. I don't require the portability or workability of a powder right now. It seems that without the special equipment, the best I can expect is a goo-ish end result. I figured, try ethanol and then I can just drink it in some grape juice. I expect to have some problems as this is new to me and I don't have any experience with shrooms except eating them... ethanol appears to be the blunt instrument. I've been reading some of your older posts on the shroomery. You mention using acetic acid and ammonia to get a good psilocin extract. I get the feeling that this is out of my reach...but I like the idea of a psilocin rich extract. I'd liketo get: A shot glass sized dose of mainly psilocin as the active. (proteins and other bits being removed not a priority) Do you think one could acidify and ethanol extraction (ala crystals of the gods) and end up with mostly pslocin? What ph do you think one should shoot for? All posts written by Madcap should be regarded as fiction.

^^If you concentrate the ethanol with acid in it you will also concentrate the acid unless its a very volatile acid. This runs the risk of letting the pH get really low to where it might cause problems both with ingestion and stability, although I can't be sure it depends on the acid and some other factors.
Regardless I'm just just a crude ethanol extract would work too. Might not be as good as methanol but ethanol is pretty close in selectivity and its easier to find for most people.

How about adding acid to an already concentrated etoh extract? I've got plenty of material to work a few different ways. I just did 't want to waste any by trying something without asking around first. All posts written by Madcap should be regarded as fiction.

Well, all the extractions in which I, or others I have spoken with, isolated the crystals from the alcohol before it was fully dried, we have found that the crystals are not active. The goodies are in the goo that evaporates on top of the crystals, which also happens to degrade very fast when exposed to the elements. When reading the patent by Heim and Hofmann, it is very involved when trying getting actual crystals of psilocybin. Without proper chemistry equipment, for people trying a methanol or ethanol extraction, don't expect the same results, because the goodies break down very quickly if not evaporated and stored properly, or at least that has been my experience. I ate some of the crystally goo after it had been left out to dry and get hard in front of a fan, and it was very weak. The mushrooms used were good quality, though.
Below is the patent:
United States Patent Office 3,183,172 Patented May 11, 1965
OBTAINING PSILOCYBIN AND PSILOCIN FROM FUNGAL MATERIAL Roger Heim, Paris, France, Albert Hofmann, Botimingen, Basel-Land, Arthur Brack, Riehen, near Basel, and Hans Kobel, Basel, Switzerland, and Roger Cailleux, Pavillons-sous-Bois, France, assignors to Sandoz Ltd., Basel, Switzerland, a Swiss firm No Drawing. Filed Feb. 16, 1959, Ser. No. 793,234 Claims priority, application Switzerland, Feb. 21, 1958, 56,143; July 30, 1958, 62,393 21 ClaIms. (Cl. 195-80)
The present invention relates to psilocybin and psilocin and to the preparation thereof from the so-called hallucinogenic fungi: Psilocybe, Stropharia, Panaeolus, Conocybe, Amanita and Russula. It has heretofore been impossible to isolate the active substance from samples of the natural fungi or from artificially cultured fungal material; nor has it been possible to culture hallucinogenically active species starting from natural fungi-under conditions that would produce active material in amounts sufficient for obtaining the active substance on a preparative scale.
A primary object of the present invention is the embodiment of an industrially feasible process whereby the hitherto unknown active principles of hallucinogenic fungal species, notably Psilocybe mexicana Heim, Psilocybe caerulescens Murrill var. nigripes Heim, Psilocybe zapotecorum Heim, Psilocybe semperviva Heim and Cailleux, Psilocybe aztecorum Heim and Stropharia cubensis Earle. are obtained free from halogen. This object is realized according to the present invention by extracting the active principals either directly from the fungal material of natural origin or from cultures of the fungi or of biological variants or mutants thereof which have been grown on natural or artificial substrates by culture techniques which make it possible to obtain sufficient amounts of active material to permit the isolation of the latter on a preparative scale. Briefly stated, the cultures are incubated in daylight or in the dark at a constant temperature between 18 and 27 centigrade and, after purification, the active substance is separated and freed from halogen, where present. The process, more specifically, may be carried out as follows: For a culture on a natural substrate, a compost consisting of fermented wheat straw and a mixture of corn leaves and corn stems or stalks of wild grasses is washed well under running water, poured into earthenware dishes and sterilized in an autoclave. The compost is inoculated with mycelium from primary cultures and incubated for approx. two weeks at 24-27 centigrade. The cultures are then covered with sterile sand and left undisturbed in a glass box in the daylight at a temperature of 18-27 centigrade, the moisture content being kept constant.
The fruit bodies appear after 4 to 5 weeks. They are harvested from time to time for a period of 1 or 2 months as soon as the formation of the spores has started. In developing an alternative process which is better adapted for large scale operation, it was found quite unexpectedly that, grown in vitro on substrates rich in nutritive material, the fungi produce active mycelium and sclerotia in large quantities and only a very small number of fruit bodies; on substrates poor in nutrients, however, the familiar fruit bodies are produced. On an agar medium containing 1.5% by weight of agar, a concentration of 0.2 to 0.7% by weight of dry substance of malt extract is the optimum for the formation of fruit bodies, whereas concentrations of 4 to 10% by weight, depending upon the particular fungal species employed, are optimal for the formation of mycelium and sclerotia.
While daylight is indispensable for the formation of fruit bodies, it has been found that sclerotia and mycelium are formed in greater profusion if the cultures are incubated in the dark. The largest yields of active fungal material (mycelium and sclerotia) are obtained by preparing surface cultures with culture media of malt extract (beerwort or commercial preparations of malt extracts) containing 4 to 10% by weight of dry substance, and by incubation of these cultures in the dark at a constant temperature between 22 and 26 centigrade. Addition of 0.2% by weight of agar to the culture medium enhances good growth. This medium is just sufficiently firm-though it is still almost liquid-to permit the fungus to grow quickly, forming a well-knit mycelium layer. Addition of ferrous salts is very desirable; addition of zinc, potassium, calcium and magnesium salts, of nitrate, phosphate and sulphate ions as well as of yeast extract or of corn steep solids are also found to be very advantageous.
This process of cultivation is a great technical improvement, as it gives a high yield of active starting material; the yield is actually ten times greater than that obtained from a culture on natural substrates and the artificial method takes less time and involves less work. The active fungal material (fruit bodies, sclerotia and mycelium) is carefully dried in an air current or under reduced pressure at 20-40 centigrade, finely ground and thoroughly extracted with a lower aliphatic alcohol or with a mixture of water and a water-miscible organic solvent at room temperature (20 to 30 centigrade). The extracts are concentrated under reduced pressure at low temperature. The residue is defatted with petroleum ether and extracted with acetone or chloroform-alcohol to remove inactive accompanying material. Other ballast material is separated off by dissolving the residue in as little water as possible and repeated precipitation with absolute ethanol or acetone; the filtrate is concentrated under reduced pressure at low temperature.
Further purification is advantageously carried out by chromatography on cellulose powder in a through-flow process; elution is performed with water saturated butanol or another alcohol not miscible with water. The fractions collected are tested for their content of active substance by means of the Keller reagent (glacial acetic acid containing iron chloride and concentrated sulphuric acid). The fractions showing a positive colour reaction are combined and, if necessary, chromatographed again on a column of cellulose powder. From the through-flow chromatogram a rather rapidly travelling zone is eluted.
This yields a product containing an active substance, "psilocin," characterized by a clear blue Keller reaction, while from a zone travelling more slowly, a product containing a second active substance, "psilocybin," is obtained in larger amounts.
The active substances are obtained in a fairly pure state from the column but contain halogen and do not crystallize out as psilocybin and psilocin. The halogen may be removed only by chemical treatment, crystalline compounds being thereby obtained. For this purpose, an aqueous solution of the active material is treated with silver carbonate or silver oxide. Excess silver ions are removed with hydrogen sulphide and the remaining solution is concentrated under reduced pressure at low temperature, the substances crystallizing out from the concentrated solution.
For analysis, psilocybin is recrystallized from methanol or water. Recrystallization from water yields very fine white needles; from methanol colourless hexagonal plates or prisms are produced; these contain methanol and melt at 195-200 centigrade (with decomposition). The compound dissolves in 120 parts by weight of boiling methanol or in 20 parts by weight of boiling water; it dissolves difficulty in higher alcohols and other organic solvents. The crystals are dried in a high vacuum at 100 centigrade, a decrease in weight of 10.4% taking place. The results of elementary analysis give the empirical formula C12H17O4N2P (molecular weight 284.2). Psilocybin is an amphoteric compound. It is optically inactive and readily soluble in dilute aqueous mineral acids and in dilute aqueous alkalis with which it forms salts. A solution of psilocybin in 80% (by weight) aqueous ethanol has a faintly acid reaction (pH 5.2). The UV-spectrum in a methanolic solution shows maxima at 222, 267 and 290 m~.
For analysis, the psilocin is purified by another chromatographic operation on a column of cellulose powder, using water-saturated butanol or by treatment with potassium bi-carbonate in an aqueous solution and extraction with ether or an organic solvent. The results of elementary analysis give the empirical formula C12H16NO2. Psilocin crystallizes from methanol or acetone; it is moderately soluble in water but dissolves readily in dilute acid. M.P. 173-176 centigrade. (with decomposition). Psilocybin is the phosphoric acid ester of psilocin 4-hydroxy-dimethyl tryptamine (Experientia, vol. 14, 1958, pages 397-399).
Psilocin is characterized by an UV-spectrum in a methanolic solution with maxima at 222, 260, 267, 283 and 293 m~ and by the Keller colour reaction which shows-unlike psilocybin-a clear blue colour. The products of the present invention are psychotropically active and find use in therapy as tranquillisers. Subcutaneous injection or oral administration of 2 to 8 mg. of psilocybin produces a pronounced euphoric mood accompanied by a lack of spontaneity and a feeling of indifference. When administered in higher dosage, there occur changes in perception together with autonomic symptoms.
Both psilocin and psilocybin are useful for research into mental disease and psychoses. They are also useful as an aid to psychotherapy in mental patients (tranquillisation, anxiety repressing, etc.). In the following illustrative examples, parts by weight bear the same relationship to parts by volume, as do grams to millilitres. Percentages are by weight. Temperatures are in degrees centigrade.
EXAMPLE 1 Psilocybin and psilocin from fruit bodies of Psilocybe mexicana Heim obtained by artificial cultivation. For cultivation on a natural substrate a compost of fermented wheat straw is prepared, washed thoroughly with running water, poured into earthenware pots and sterilized in the autoclave. The compost is inoculated with mycelium from primary cultures of Psilocybe mexicana Heim and incubated for approx. two weeks at 24-27 centigrade. The cultures are then covered with sterile sand and left in a glass case at a temperature of 21-22 centigrade in the daylight. After 4 to 5 weeks the fruit bodies appear when the spores are beginning to form, the fruit bodies are gathered from time to time over a period of I to 2 months. The ripe fruitbodies of Psilocybe mexicana Heim are then, carefully dried in an air current at 30 centigrade. 54 parts by weight of the dried fungi are finely powdered and extracted once with 600 parts by volume and three times with 300 parts by volume of methanol for 30 minutes each time. The extracts are combined and evaporated to dryness in vacuo. Residue: 12 parts by weight.
To defat the methanol residue, it is rubbed four times with 250 parts by volume of petroleum ether and three times with 100 parts by volume of chloroform containing 10% of ethanol. The undissolved residue of approximately 10 parts by weight is dissolved in 10 parts by volume of water and the solution is mixed gradually with 100 parts by volume of absolute ethanol. The amount of active substance in the solution is thereby increased. This operation is repeated two or three times. The solutions are decanted off and evaporated to dryness under reduced pressure; the residue is again dissolved in methanol and the solution treated with 20 parts by weight of cellulose powder containing 5% of water. The methanol is evaporated off under reduced pressure and the cellulose powder bearing the active material is poured onto a column of 100 parts by weight of cellulose powder containing 5% of water, the column having previously been washed with water-saturated butanol. The column is eluted with water-saturated butanol and fractions of 20 parts by volume are collected.
The evaporation residues from the individual fractions are tested for their content of active material by means of the Keller colour reaction. For this purpose, 2 millilitres of Keller reagent are added to samples of 0.25 milligram of evaporation residue.
The fractions showing a positive colour reaction are combined. The amorphous powder is dissolved in 20 parts by volume of water and shaken with 0.5 parts by weight of silver carbonate. The solution is filtered and desilverized with hydrogen sulphide and then carefully concentrated. Psilocybin crystallizes from the concentrated solution in the form of fine colourless needles (yield 200 parts by weight).
Psilocin is obtained only in trace amounts from the fruit bodies. Psilocybin is obtained in an analytically pure state by a further recrystallization from methanol or water. It dissolves boiling methanol or in water at the boiling point. Colourless prisms are obtained from methanol, which melt at 195-220 centigrade (with decomposition). The results of elementary analysis give the empirical formula C12H17O4N2P. The UV-spectrum in a methanolic solution shows the following maxima: 222 mjs, 267 m~s and 290 m~. The new substance is amphoteric. It dissolves to form salts in diluted aqueous alkalis as well as in aqueous acids. A solution of psilocybin in 80% aqueous alcohol has an acid reaction, (pH 5.2).
EXAMPLE 2 Obtaining psilocybin and psilocin from Stropharia cubensis Earle obtained by artificial cultivation The fruit bodies of Stropharia cubensis Earle collected in Mexico are carefully dried at room temperature in a shady place in the air. 24.2 parts by weight of dried fruit bodies are thoroughly ground and extracted once with 300 parts by volume and then three times with 150 parts by volume of methanol, each time at room temperature for 30 minutes. The extracts are combined and evaporated to dryness under reduced pressure. The residue (6 parts by weight) is defatted by rubbing well four times with 125 parts by volume of petroleum ether and three more so times with 50 parts by volume of chloroform each time, the chloroform containing 10% of ethanol. The undissolved residue (59 parts by weight) is dissolved in 5 parts by volume of water. From this solution other products are precipitated by slowly adding 50 parts by volume of absolute ethanol so that the active substance accumulates in the solution. The purification is repeated two or three times in the same manner. The decanted solutions are combined and evaporated to dryness in vacuo. The residue is taken up in methanol and treated with 10 parts by weight of cellulose powder containing 5% of water. The methanol is evaporated off under reduced pressure and the cellulose powder bearing the active substance is poured onto a column of 50 parts by weight of cellulose powder containing 5% of water, the column having previously been washed with water-saturated butanol. After extraction with water-saturated butanol, fractions of 10 parts by volume are collected. The individual fractions are evaporated in a high vacuum at a maximum bath temperature of 50 centigrade and are tested for their content of active material by means of glacial acetic acid containing ferric chloride and concentrated sulphuric acid. For this purpose, 2 millilitres of Keller reagent are added to samples of 0.25 milligram of the residue. The active fractions are characterized by a violet (psilocybin) or a clear blue (psilocin) Keller reaction. The fractions showing a positive colour reaction of the same shade are combined. The amorphous powder of the above evaporation residues is dissolved in 2 parts by volume of water and extracted with 0.25 parts by weight of silver carbonate. After filtering, the excess of silver ions is removed with hydrogen sulphide. Upon carefully concentrating the solution, the psilocybin crystallizes as thin colourless needles.
EXAMPLE 3 Obtaining psilocybin and psilocin from pure cultures of Psilocybe semperviva Heim and Cailleux (a) PREPARING THE INOCULATION MATERIAL Pure cultures of the basidiospores of the Mexican fungus Psilocybe semperviva Heim and Cailleux are grown on beerwort-agar. For this purpose, the spores falling from the lamellae of a ripe fruit body are collected on sterile material, placed on beerwort-agar and incubated. From the primary cultures so produced the inoculation material is prepared in the following manner in sufficient amount: The mycelium is scraped off with a rough spatula, a suspension of fine mycelium flakes being formed. This suspension is used to inoculate flasks containing a culture medium and saddle-shaped porcelain filters such as are used for filling distillation columns.
The best results are obtained with 300 millilitre flasks containing about 50 saddle-shaped filters (size 1 cm., weight approx. 0.9 gram) and 80 millilitres of a culture medium consisting of beerwort containing approx. 4% of dry substance and 0.2% of agar. The culture is incubated at a temperature of 24 centigrade. After 2 weeks a compact mycelium layer has formed on the surface. The whole culture is shaken for 30 minutes on the rotating shaking machine, the sharp edges of the saddle-shaped filters grinding the mycelium so that a fine suspension of mycelium flakes is formed. The inoculation material so obtained is sufficient to inoculate 50 litres of culture medium.
(b) PREPARATION OF CULTURE Fresh and clear beerwort, without hops, is diluted with tap water to a content of 8% of dry substance. To each litre of this solution there are added: Ingredient Amount (grams) FeSO4 ° 7H20 0.00417 ZnSO4 ° 7H2O 0.00172 Ca(N03)2 1.0 KH2PO4 0.0624 MgSO4 ° 7H2O 0.0624 KCl 0.0312 Agar-agar 2.0 This culture medium is poured into penicillin flasks and the latter are then sterilized in the autoclave at 108 centigrade for 25 minutes. On cooling, the flasks are each inoculated with 2 millilitres of a suspension of Psilocybe semperviva Heim and Cailleux. The cultures so obtained are incubated in the dark at 24-26 centigrade, the mycelium layer described under 3(a) thus being formed.
(c) ISOLATION OF THE FUNGAL MATERIAL After 7 weeks the ripe culture is filtered through a gauze tissue, the fungal material is squeezed out and dried in vacuo at 30 centigrade. 2540 grams of dry material, i.e. 25.4 grams per litre of culture medium are obtained after 49 days from a batch of 100 penicillin flasks containing 100 litres of culture medium. The culture filtrate containing active material is worked up according to the procedure described in the following paragraph for the fungal material.
(d) OBTAINING THE ACTIVE MATERIAL 306 parts by weight of the dried fungal material are finely powdered and shaken 3 times with 500 parts by volume of chloroform each time and 3 more times with ~500 parts by volume of chloroform containing 10% of ethanol. 2.8 parts by weight of inactive accompanying substance are thereby dissolved. The pre- extracted fungal material is thoroughly extracted once with 3000 parts by volume and 3 times with 1500 parts by volume of methanol each time. The combined extracts are evaporated to dryness under reduced pressure, a clear brown residue of 17.5 parts by weight remaining. In order to remove fatty impurities from this residue, it is taken up in 17.5 parts by weight of water and the suspension is extracted once with 500 parts by volume and twice with 250 parts by volume of petroleum ether each time. The petroleum ether solution contains 0.75 parts by weight of inactive accompanying material. The residual aqueous solution is concentrated under reduced pressure to about 25 parts by volume and is then treated with 250 parts by volume of absolute ethanol, while being vigorously stirred. From the sticky precipitate so produced, the solution containing active material is separated by decantation. The precipitate is redissolved in a little water and treated with a tenfold quantity of absolute ethanol. This purification by precipitation is repeated twice with the residue. The solutions are combined and evaporated to dryness in vacuo. There remains a solid residue of 11.7 parts by weight containing the whole amount of active material. For chromatography on a column of cellulose, the residue is dissolved in as little of 50% methanol as possible.
The solution is mixed well with 40 parts by weight of cellulose powder and the material is dried under reduced pressure. The cellulose powder bearing the active substance is poured onto a column of cellulose prepared by suspending 350 parts by weight of cellulose powder in water-saturated butanol. The column is developed in a through-flow process with water-saturated butanol, fractions of 100 parts by volume each being thereby separated and then concentrated under a high vacuum at a bath temperature not exceeding 50 centigrade. The intermediate fractions (3.35 parts by weight) show a positive Keller colour reaction and are chromatographed again in the same way for further purification.
Fractions of 50 parts by volume each are obtained by developing with water-saturated butanol and, after evaporation in a high vacuum at a bath temperature not exceeding 50 centigrade, are tested by means of the Keller colour reaction. The fractions obtained are as follows: Fraction No. Residue parts by weight Keller colour reaction 1-7 1.27 Negative 8-16 0.087 Clear blue 17-20 0.079 Negative 21-30 1.053 Violet 31-43 0.758 Negative Upon treatment with silver carbonate, the residue of fractions 8-16 yields 0.045 part by weight of pure psilocin as described in Example 2. Fractions 21-30 yield 0.765 parts by weight of pure psilocybin after treatment with silver carbonate.
The active material is obtained from the culture filtrate by the same process. For this purpose, the filtrate is concentrated in vacuo to approx. 1/10th of its volume. It is then precipitated with a tenfold volume of methanol and filtered off from the precipitated accompanying material. The solution is evaporated to dryness in vacuo and the residue is extracted 3 times with a tenfold amount of methanol. The evaporation residue of the methanol extracts is worked up as described above. 80 milligrams of psilocybin and 6 milligrams of psilocin are obtained from each 12 litres of culture filtrate.
EXAMPLE 4 Obtaining psilocybin and psilocin from pure cultures of Psilocybe mexicana Heim In this example a detailed description is given of the cultivation of Psilocybe mexicana Heim in vitro for the production of mycelium and sclerotia as well as of the method of obtaining the pure active material. Fresh and clear beerwort, without hops, is diluted with tap water to a content of 4.0-4.5% of dry substance. To this solution there are added: Ingredient Amount (grams) FeSO4 ° 7H20 0.00417 ZnSO4 ° 7H2O 0.00172 Agar-agar 2.0 500 millilitre portions of this culture medium are poured into 1.6 litre Fernbach flasks and the latter are then sterilized in the autoclave at 108 centigrade for 25 minutes. On cooling, the flasks are each inoculated with 2 millilitres of a suspension of the fungus Psilocybe mexicana Heim. The inoculation material is prepared by growing pure cultures of basidiospores of the said fungus on beerwort agar. The spores falling from the lamellae of a ripe fruit body are collected on sterile material, placed on beerwort-agar and incubated. From the primary cultures so produced the inoculation material may be prepared in the following manner: The mycelium is scraped off with a rough spatula under a stream of sterile tap water. In this way a suspension of fine mycelium flakes is obtained. This suspension is used to inoculate Erlenmeyer flasks containing a culture medium and saddle-shaped porcelain filters. The best results are obtained with 300 millilitre Erlenmeyer flasks containing a 50 gram saddle-shaped filter (size 1 cm., weight approx. 0.9 gram) and 80 millilitres of a culture medium consisting of beerwort containing approx. 4% of dry substance and 2% of agar. The culture is incubated at a temperature of 24 centigrade; after 2 weeks a compact mycelium layer has formed on the surface. The whole culture is shaken for 30 minutes on the rotating shaking machine, the saddle-shaped filters grinding the mycelium so that a fine suspension of mycelium flakes is formed. The inoculation material so obtained is sufficient to inoculate 25 litres of culture medium. The inoculated cultures are incubated at 24-26 centigrade in the dark. A mycelium layer bearing many sclerotia is formed, the sclerotia in general reaching a size of 1 cm. (some of them may grow even larger). In order to separate the mycelium and the sclerotia, the ripe cultures are filtered through a gauze tissue, squeezed out and dried in a drying oven at 35-40 centigrade. 1149 grams of dry material (sclerotia and mycelium), i.e. 17.14 grams per litre of culture medium are obtained after 62 days from a batch of 134 Fernbach flasks containing 67 litres of nutrient solution.
The active material can be obtained as follows: 612 parts by weight of dry substance consisting of dried sclerotia and mycelium are finely pulverized and pre-extracted three times with 1000 parts by volume portions of chloroform and three times with 1000 parts by volume portions of chloroform containing 10% of ethanol. 5.6 parts by weight of inactive accompanying material are thus pre extracted. The pre-extracted fungal material is then extracted thoroughly once with 6000 parts by volume and three more times with 3000 parts by volume of methanol. The combined methanol extracts are evaporated to dryness under reduced pressure to give 35 parts by weight of a clear brown residue. In order to remove fatty impurities from this residue, it is washed in 35 parts by volume of water and shaken once with 1000 parts by volume and twice with 500 parts by volume of petroleum ether. The petroleum ether contains 1.5 parts by weight of inactive accompanying substance. The remaining aqueous solution is first concentrated under reduced pressure to approx. 50 parts by volume and is then treated with 500 parts by volume of absolute ethanol with vigorous stirring. From the sticky precipitate so produced, the solution containing active material is separated by decantation. The precipitate is redissolved in a little water and treated with a ten-fold amount of absolute alcohol. This purification by precipitation is repeated twice with the residue. The solutions are combined and evaporated to dryness under reduced pressure. There remains a solid residue of 23.4 parts by weight containing the whole amount of active material. For chromatography on a column of cellulose, the residue is dissolved in as little of 50% methanol as possible.
The solution is mixed well with 80 parts by weight of cellulose powder and the material is dried under reduced pressure. The cellulose powder bearing the active sub stance is poured onto a column of cellulose prepared by suspending 700 parts by weight of cellulose powder in water-saturated butanol. The column is developed in a through-flow process with water-saturated butanol, fractions of 200 parts by volume being thereby separated and then concentrated under a high vacuum at a bath temperature not exceeding 50 centigrade. The fractions obtained are as follows:
TABLE 1 Fraction No. Residue parts by weight Keller colour reaction 1-14 2.170 Negative 15-34 6.650 Positive 35-40 3.540 Negative 12.370 Approx. 11 parts by weight remain in the column. Fractions 15 to 34 yield a residue of 6.660 parts by weight and contain the whole amount of active substance. They are chromatographed again as described below for further purification. The residue of 6.660 parts by weight is dissolved in as little methanol as possible and is then used to impregnate 20 parts by weight of cellulose powder. After drying, the cellulose powder is poured onto a column of 600 parts by weight of cellulose powder, which has been treated as described above. Fractions of 100 parts by volume each are obtained by developing with water-saturated butanol and, after evaporation in a high vacuum, are tested by means of a colour reaction. The fractions obtained are as follows:
TABLE 2 Fraction No. Residue parts by weight Keller colour reaction 1-8 2.950 Negative 9-17 0.180 Clear Blue 18-21 0.155 Negative 22-31 0.912 Violet 32-45 1.510 Negative The residue from fractions 9-17 yields 0.090 part by weight of pure psilocin after treatment with silver carbonate as described in Example 1. After treatment with silver carbonate as described in Example 1, fractions 22-31 (Table 2) yield 0.619 parts by weight of pure psilocybin having the properties described in Example 1.
The active material is obtained from the culture filtrate by the same process as described above for the sclerotia. For this purpose the culture filtrate is concentrated under reduced pressure to approx. 1/10 of its volume. After precipitation with a tenfold volume of methanol and subsequent filtration, the residue is extracted three times with a tenfold amount of methanol. The evaporation residue of the methanol extracts is worked up as described above. From every 10 litres of culture filtrate 220 milligrams of psilocybin and 12 milligrams of psilocin are obtained
EXAMPLE 5 Psilocybin and psilocin from pure cultures of Stropharia cubensis Earle A culture medium is prepared as follows: Fresh and clear beerwort, without hops, is diluted with tap water to a content of 6% of dry substance. To each litre of this solution there are added: Ingredient Amount (grams) FeSO4 ° 7H20 0.0021 ZnSO4 ° 7H2O 0.0009 Ca(NO3)2 1.0 KH2PO4 0.0624 MgSO4 ° 7H2O 0.0624 KCl 0.0312 Agar-agar 2.0 This culture medium is sterilized as described in Example 3 and inoculated with 2 millilitres of a suspension of the fungus Stropharia cubensis Earle (from Kambodscha) per litre of nutrient solution. The inoculation material is prepared as described in Example 3a. After incubation for 52 days at 24 centigrade in the dark, there are obtained 452 grams of dried fungal material, i.e. 22.6 grams per litre from a batch of 20 litres. The active substance is obtained from the fungal material in the manner described in Example 3. Yield: 1083 milligrams of pure crystalline psilocybin and 45 milligrams of psilocin.

I tried methanol extraction with great success. Still there are a few questions. 1. Finely ground 30 g of PC were extracted with 500 ml of hot methanol in a Continuous Solid-Liquid Extractor for ~1 hr. 2. Approx, 350 ml of methanol were distilled off in a simple distillation setup. 3. The remaining 100 ml of thickish yellow liquid were put in a vacuum desiccator and dried under water aspirator vacuum. 4. In 2 hours there were ~ 20-25 ml of thick yellow goo with some whitish flaky sediment at the bottom. 5. It has been decided to move the product to a more suitable container for future experimentation. Some goo stuck to the evaporation cup. An attempt to wash it with alcohol failed, so I decided to wash the cup with hot water. On second thought I decided not to discard the wash but make a tea by adding some honey. It seemed that the amount of extract that stuck to the evap cup was very small and I was sure that I would not even notice any affects. Boy, how wrong I was! Luckily I did not have enough time to go to a bar as I originally planned. The tea kicked in in less than 15 min. In 30 min I was peaking. Not knowing how high I'm gonna get I panicked. For 2 hours it has been very intense. The comedown lasted for another 6 hrs. What a surprise! I've got another 20 ml of the yellow goo in my storage container . Questions: 1. Is it possible to dry extracts even further so I can weigh it? Rotovap maybe? Then how do I get the extract from the evaporation flask? 2. What is the liquid part of the goo? That is not methanol for sure. 3. Is psilocybin in this goo stable? I keep it in a fridge. Do not seek the truth, just drop your opinions.

So would this work as a pretty good, clean methanol extract of psilocybin?-30 grams of dried mushrooms are finely ground up. -Mixed once with 400ml and three times with 200ml of Naptha. Stirred for ten minutes each time using magnetic stirrer. -Plant material is then filtered out and dried. -Dried material is then placed in 500ml of methanol. Stirred for 6 hours at room temperature. -This is then repeated once more with fresh methanol. -Methanol extracts combined and dried in a 40 C bath (pyrex dish) with fan. -Brown residual extract is then dissolved in warm water. Naptha is added and this is stirred for thirty minutes and repeated two more times with fresh naptha. Naptha is discarded. -Water is then mixed vigorously with ten times by volume of methanol until fatty precipitants occur. Precipitant is then decanted for further extraction and the methanol is set aside safely. -The precipitate is redissolved in a little water and treated with a tenfold quantity of methanol until precipitants occur. -The methanol solutions are combined and evaporated to dryness in in a warm bath under a fan out of direct light. There remains a solid residue containing the active material, or so we hope. What do you think? Any imput would be great. Test to come of this next week, or so we all hope. Damiana PEACE

It is a standard lab glass or plastic airtight vessel that you can connect to a source of vacuum (water aspirator in my case). When vacuum is turned on it sucks off the solvent molecules, or molecules of any liquid thus drying the product. Your product is placed inside the desiccator in a wide cup. Additionally you may use some drying agents for better drying. Next time I'll use a use a Rotovap. damiana wrote:Also, can you explain your distillation setup?
That's been the most basic distillation setup (a boiling flask heated by a regulated hotplate + a distillation head with a thermometer + a Liebig condenser + collection flask immersed in cold water). Do not seek the truth, just drop your opinions.

1. probably not, that's what I did. you'd need to apply a solvent partition extraction, or chromatography, to separate what are likely proteins bound to the alkaloids. 2. see 1. 3. psilocybin is rather stable, it's psilocin that is subject to degradation.

Benzyme, can you please explain what you believe the best/suitable process would be for the solvent partition extraction? (SWIM has no Chomatography equipment) Would what I described above work -> dissolving goo in water and defatting with Naptha, separating water from naptha, adding tenfold Methanol to water until proteins and fats are participated out, and then evaporating the decanted methanol to obtain relatively clean psilocybin? Your response, or anyone who is well informed on this matter, would be well appreciated. Mahalo, Damiana PEACE

So, swim did a little experiment. Grinded four grams up. Mostly powder but some small pieces still, no bigger than sunflower kernel. Weighed again and noticed it lost .1 grams so swim added that back and placed total amount in jar. 100 ml of methanol was added and this was magnetically stirred for 8 hours. The powder was than vacuum filter out and methanol evaporated in a 40c bath with a fan blowing on it. Evaporated to a dried, non-sticky, mushroom smelling clearish yellowish thin gel. Warm water was added but not everything dissolved in water. This was than mixed with heptane for ten minutes, which clearly dissolved the whitish fats and become a milky color. Heptane was separated and water was mixed with methanol. A milky fatty substance did indeed precipitate out. This was filtered and the methanol/water is now evaporating at room temperature under a fan. If anything is in this dish swim will try 1/8 of its final weight, approximately .5 grams of mushrooms is the expected equivalence. UPDATE (7/3/2012)
The dish evaporated. SWIM found a very hard, yellowish tar. This is like summer heat has just softened your rock hard candy and there is only about 100mg max of this on the dish, very little. SWIM did not weigh it. SWIM added 80 proof vodka and scraped it up until it all dissolved into the vodka, which it did nicely enough. This was then vacuum filtered, and hair and dust was removed. Now SWIM is left with about 75ml of vodka that looks like anejo patron because of its yellow/gold hue. It is obviously still not pure because there is a color, but SWIM is assuming it is maybe 50% pure. Which is to say that this tar is possibly made up of 50mg of psilocybin. This would be two medium-strong doses. Which is how SWIM thinks of a four gram sack of mushrooms, two medium-strong doses. SWIM has not bio-assayed this vodka yet, and is not going to be able to for five days. Update to come. PEACE

Okay, well I know I said the extract would be tested. Very obviously SWIM is unable to try it himself at this time because of school work. He is also reluctant because he truly believes it worked and that the trip will be very clean and intense, so SWIM wants to wait for the right time to try it. I'm sure if anyone else tried this tek above they could achieve results. At least I hope this tek works. If SWIM ever bio-assays this, a report will come! Damiana PEACE

idk. theoretically, the phosphoryloxy bond would break with high enough heat, i.e. decomposition. there are boiling points listed at reduced pressure, obviously that doesn't help. of course, there are sparce reports of successful vapes, but I've never tried it. If I had enough to work with, I'd extract with heated ascorbic acid in methanol, then evap under reduced pressure. scrape the product, and vape (it would require higher heat to dissociate, since it would be a salt). A/B with psilocybin/psilocin is tricky, it has two groups with different pKa's. it's a suitable method for analysis, but may or may not yield an active product.

I'm no chemist, but I am almost done with my engineering degree. This statement grabbed my interest: Quote:there are boiling points listed at reduced pressure, obviously that doesn't help. Do you suppose some type of device could be made to reduce ambient pressure to lower the temperature required for vaporization? I know the main issue with vaping psilocybin'psilocin is freebasing it, and how fragile it seems to be when this is attempted. Is it more likely to get vaporized psilocin at lower pressure? Am I way out there on this one? Be an adult only when necessary.
