Great job rom! I'd go for the FASI salting

I do now a quick water wash...

Anyway I'm not even sure that iboga TA alkaloids are salts, they might just be free bases so in the end if this tek is
as efficient as the one used by iboga TA suppliers it would be very interesting financially since 40g costs 130€ at ibogaworldand and got you a solid 8g while 4g TA costs more
than 180€ from the same supplier, it's incredible what they charge for extracting That must be really easy money for them...

In this picture, we have the resulting liquid that now may be discarded, and the solids, TA in their freebase form.

The water wash part was just :

- Add de-ionised water to this extract, mix it and filtering it through coffee filter or vacuum system.
- The collecting solids are freebase so they don't dissolve in water.
The yield is now reduced to 3,2 grams (see picture).
- The yellow liquid is the impurities dissolved in water (see picture again).

So this number is now more in line with the 5 to 10% alcaloids in rootbark.

Next step, bioessay !

The HCl salts are much more stable and will keep their potency if one is going to store them for later use. If one wants a more complete TA with all the alkaloids, I would suggest doing the Acetone/HCl step, then just evaporating the acetone from the crystals (rather then separating the crystals from the acetone to dry), as this will leave the other alkaloids in, while the alkaloids that will form a salt with HCl stay in HCl form. This will at least allow the most important alkaloids to remain much more stable, making for a more potent extract, especially if it's to be stored for any length of time.

SALTING :

The Freebase TA, weighed 3,2 grams was dissolve in acetone.

We know Ibogaïne, Ibogaline, Ibogamine bounds to hydrochloric acid but other alcaloids don't.
So, to preserve a fuller spectrum, we decided to salt with HCL but to save the other alcaloids left behind in acetone, in order to add them to the HCL salts.

The hydrochloric acid was added to acetone iboga freebase dissolved.

We see some alcaloids crushing.

This acetone acid solution will be let in fridge overnight to further salt.

Thanks for continuing the work rOm! might i ask, where do you have the info about the alkaloids that dont bind to HCl? What other alkaloids are they?

The present investigation of Tabernanthe iboga root records the isolation of twelve compounds, which includes not only the four known alkaloids ibogamine, ibogaine, tabernanthine and iboluteine but also iboquine, desmethoxyiboluteine, the hydroxyindolenine derivatives of ibogaine and ibogamine, voacangine, gabonine, kisantine and kimvuline. Of these, the latter three have not been described previously. The current interest in Tabernanthe iboga initiated a more detailed investigation of the alkaloidal content of the root. Emphasis was placed both on the preparation of the major alkaloids in a state of high purity and on the isolation of the greatest possible number.

250 mg of this TA was bioessayed. The effects are very clean and somewhere equal in potency to 2 grams of this rootbark.

Good day!
Thank you, rOm and GratefulDad and other nexians for these extraction teks!


Could you please answer some questions of mine

0. So how much vinegar/HCl4.0 should be added for pulls (on 40g bark: rOm - ~30ml, GD - ~200ml - quite a big difference or the HCl step accounts for it...)?
1. Why in rOm's tek to do 2 pulls with vinegar and then 2 pulls with HCl - why not only vinegar or only HCl?
2. Why in rOm's tek the pH of HCl solution for pulls should be 4.0? ('cause the crystals will precipitate?)
3. Will in GratefulDad's tek this procedure significantly (to say >1%) decrease the yield?

Hope the Q's are not too stupid

You have any pics of the PTA after acetoned and filtered?

TA extract, PE extract, these abbreviations, what do they stand for please? Searched google and wiki here, could not find anything close to it. Thanks!

TA stands for total alkaloid (aka full spectrum)

Thanks, it seems "PE (extract)" means Plant Extract, I thought TA and PE referred to specific extraction tecs, was clearly searching to far for an explanation

No, but I plan on really digging this whole Iboga culture and extraction a lot more.

Hi all,

This sounds like a good tek. I did with ammonia, but it is not good for two reasons, it smells to much and in building situation it is not good. Second the TA forms on top and separation is hard.

NaOH is great idea but I didn't see washing off with H2O? As in this tek I assume that it will be highly NaOH contaminated?

Would washing dissolve some of the alkaloids like in harmala extractions.

Thanx

according to this, freebase ibogaine is insoluble in water so in theory washing it with a bit of water should remove NaOH and not lose significant amounts of alkaloids.

As mentioned by pm, just talking theory here, I have no experience with ibogaine extraction. Maybe someone else can chime in.

Hey Jox,
I have washed the freebase in water and the numbers got down by half. Before washing thr FB with water we got 8 grams raw TA, after rincing we got 3,8 grams of TA.

It is very important to think about cleaning the product, as these strong freebase are very toxic.
I would call for an safer alternative freebase such as sodium carbonate next time I make TA.
White distilled vinegar or glacial acetic acid as acid and sodium carbonate as freebase.

Kind regards,

rOm

Hi rOm,

Do you think by washing TA with water you washed out some active ingredients. I do remember that TA is not soluble in water and endlessness got us a link for reference.

Neutralising vinegar with sodium carbonate, asks for a lot of the base, maybe do one step with NaOH, filter and re dissolve with vinegar and get freebase with s.carbonate.

But I still think that washing with water is OK.

What do you think?
