Thank you for this tek. This is useful stuff indeed! Three questions though:
- What was the final yield you obtained from this?
- What is 2250 d- h2o?
- In the extraction step I wonder if you think the following alternative way might work too?
1) Do a total extract of the rootbark with a soxhlet (and methanol?) to begin with (I never
had good luck with filtering plant sludge through a filter... Then evaporate off rhe MeOH dissolve the resulting solids in some disted water. Add an excess of NaOH (to make the pH about 13 or 14 so that now all alkaloids are in their freebase form.
3) Now use HCl or vinegar to drop the pH to about 6 (the pKa of Ibogaine is about 8.1). This should protonate (salt) most of the Ibogaine, while leaving most of the alkaloids of lower pKa in their freebase from.
Extract with a non polar solvent of your choice a few times, and keep the aqueous layer. (The organic layer will contain alkaloids of higher pKa tha. Ibogaine)
4) Add NaOH to the aqueous soluthion you collected until its pH is about 8 (this should leabe most of the Ibogaine protonated, but freebase alkaloids of pKa lpwer than 6). Extract the aqueous layer into a nonpolar lauer a few times and discard. Collect the aqueous lauer.
At this point you should have removed most alkaloids that habe a pKa which is +/- that of Ibogaine.
5) If you have a way to gently evaporate off the water you can do that now. (Maybe by gently heating it but be careful not to burn the solids that remain)
6) now you should have Ibogaine.HCl.
7) To remove any ecess impurities, you can probably do what was suggested in the previous tek and wash the solids with acetone. (But leave out the HCl adding step, since your ibogain is already the hydrochloride salt.)
Recrystalise from acetone.
Again thank you for this tek! This is most useful!

and some more ino over it (alot)
linkhere it is the extracton of 500gr T.iboga
matirials
540ml of
household (5%) amonia / 25-30% amonia
x9 750ml of vinegar (at 5% acidity)
hydrochloric acid
acetone
x9 2250 d- h2o
500gr T. iboga rootbark
1. mix 750ml of vinegar with 2250ml d- h2o.
2. vinegar and water are added to the powder rootbark, the
mixture is stirred enough to thoroughly wet the powder
3. let it sit for 1 houre stirred every fifteen
minutes.
4. filter the salution tru a filtering system
5. repeat stap(1-4) 9x
6. each extract
should be made basic with ammonia at the rate of 60 mL of 25-30% ammonia, or 360
mL of 5% ammonia, for each kilogram of root. This should correspond with 60 mL
of 25-30% ammonia for each 500 mL of 5% strength vinegar used for extraction.
7. filter solits.
and let it dry
8. chrush the dryt solits. the end powder is colt "TA"
9. put the powder in a filter and add Acetone tru it.
(15 milliliters per gram of TA)
10. sture the acetone and add hydrochloric acid (one milliliter for each six grams of
TA) is added in small portions, slowly, until the precipitation of solid begins
11. please the salution in the refrigerator over night.
12. filter the the solets and let it dry
now u wil have a almost pure ibogeine extract Al
