Second (more involved) option, for much more pure TA:
Okay so you have your brown precipitate in your coffee filter, now dried up, from the first portion of the extraction.
1: You now, take your acetone and add 15-18 mls of acetone per gram of freebase TA extract (brown freebase powder), and soak freebase in the filter with it. You can stir around the precipitate in the filter (again be careful not to poke a hole in it), and wash it two or three times with the SAME acetone. Do not go over 18 mls per gram of brown TA freebase, but be sure to soak as much color from the solid as possible. The filter should contain any bark crud, and any other impurities, when finished.
This will remove the alkaloids from the solid filtrand (insoluble plant gunk that’s left in the filter), since the freebase is soluble in acetone. Chris Jenks says about 50-60% of the crud is left behind as insoluble plant material.
2: Take your muriatic acid (hydrogen chloride in a water solution, aka hydrochloric acid in solution), and add it very slowly, to the acetone. You must do this drop wise, and watch as the precipitate forms. (One milliliter for each six grams of TA) is added in small portions, slowly, until the precipitation of the solid begins.
If you own a pH tester, when the acetone is at pH 6.1, 99% of the ibogaine should be converted to the HCl salt form, and precipitate out, or be caught in the tiny amount of water that the HCl is mixed with (with 1 ml of muriatic acid, the water is negligible). This can be filtered out, and the tiny bit of water separated, and left to evaporate to be sure to recover all the iboga alkaloid HCl salts (wasn’t necessary for me).
Adding too much acid with water can start to redissolve the iboga TA HCl. You can add a few drops at a time, and watch as the precipitate forms. When it stops forming, you can place this into the fridge, to chill for a few hours (overnight may be better), before filtering, and this will increase the yield.
3: Filter out the iboga PTA HCl.
This is nearly pure TA HCl, but there may be a bit left in the acetone, and other residual alkaloids will also be in the acetone.
You can evaporate some of the acetone with a fan and low heat (no flames please), then remove any acidic water from the acetone, and let it evaporate to collect anything there. (Drying the acetone with anhydrous epsom salts, aka magnesium sulfate, or anhydrous calcium sulfate, then filtering them out by pouring the acetone through a coffee filter can be done instead of separating and evaporating any extra water but doesn’t increase the yield much, according to Chris.)
Then treat the reduced (possibly dried) acetone with the muriatic acid again (a drop or two), and harvest any more crystals of iboga PTA HCl that precipitates. Filter it out as well and add it to the first precipitate.
Another option would be to gas HCl acid though the acetone to precipitate the iboga PTA HCl crystals, but this can be covered later, if anyone is really interested. I haven’t tried this with ibogaine HCl, but am pretty sure it’d work fine, although it is more difficult and requires a few more supplies.
4: (Optional and only needed if going for pure ibogaine HCl) If you would like pure ibogaine HCl, without the other alkaloids, you can take the iboga TA HCl crystals, and dissolve it in boiling ethanol.
The boiling ethanol should be added drop wise, just until all the ibogaine HCl has dissolved.
5: This ethanol solution is then left to cool in the fridge and the ibogaine will recrystallize.
This will make the ibogaine HCl form much more pure crystals and can remove some of the ibogamine/ibogaline if still present in the precipitate.
It is not necessary unless going for 98%+ purity, and repeated recrystallization can yield very pure ibogaine HCl, but can cost a bit of yield. The ibogaline and ibogamine have very similar action as ibogaine and may also provide similar effects, so are fine for using for a session.
(There are more added notes below for those chemistry nuts that want PURE ibogaine HCl.)
When this is dry, it is ready to take.
6: (Optional, for those who would like the PTAA) For those who want to recover all the alkaloids, so they can take a complete total alkaloid extract (or Purified Total Active Alkaloid extract, aka PTAA) of high purity, they should take the acetone that they salted/precipitated out the ibogaine HCl, and evaporate it in front of a fan with warm air current.
The resulting leftover alkaloids will be an unstable oil.
7: Dissolve this oil in distilled water.
You will again see the freebase residual alkaloids precipitate out of the water/ammonia solution.
8: Add ammonia to this water with the oil dissolved into it.
9: Filter out the freebase alkaloids, and rinse again thoroughly with distilled water.
10: Let the freebase residual alkaloids dry completely.
You can then add your freebase residual alkaloids to your PTA HCls, and capsulize it. Freebases will be converted to the HCl salts in your stomach, so turning them into the HCl salt before ingesting is probably unnecessary.
This Purified Total Alkaloid extract, or PTA, should be considered very pure, and a 15-20 mg/kg dose of this (mainly for addiction treatment at this level) is just as powerful, if not more so, as the pure ibogaine HCl, so estimate your dosage with this extract accordingly. This is powerful medicine and going higher than 25 mg/kg could cause complications, so don’t be a hero. This also lasts in the system for months, so it’s recommended not to take another flood dose within 60-90 days minimum, to be safe.
