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 donβt see how dissolving in acetone will help with purification. Regardless, this method yields freebase harmalas that are (based on color) reasonably free of impurities.
