Is Caapi Extraction as Easy as it Seems?

Migrated topic.

Yeah, your right that could get rid of the mystery precip. I sort of assumed that if some plant material was in solution, but precipped in basic solution, it would be soluble in acid, even though some stuff clearly doesn't make it into the acid solution. My chem isnt good enough to really understand that kind of conditional solubility. Still, I wonder if the FB harmalas are soluble in acetone.. it could be a good way to clean/purify further.

I think freebase harmalas are somewhat soluble in acetone, but no doubt most impurities are also soluble. I don’t see how dissolving in acetone will help with purification. Regardless, this method yields freebase harmalas that are (based on color) reasonably free of impurities.

if i dont have naoh readily available can this tec be achieved with calcium carbonate or calcium hydroxide?

I believe that some have tried it with bases other than NaOH, with mixed results.
 
It's hard to tell without knowing the pKa of THH and other trace compounds, but sodium carbonate works fine with rue extractions which are more or less the same alkaloids.

Any Larry, Harry and Jones can get his mits on sodium carbonate.
