At least so far from my first experiment, there seems like there might be a little trouble getting all the caapi alkaloids to precipitate in this manner.
Approximately 1 gram of Freebase Caapi Harmalas were dissolved in hot-vinegar-water and then precipitated using the standard 10/100 salt/water ratio respectively.
This was after attempting to use 20/100 salt/water ratio. Figuring that solubility of salt in water is approximately 36/100, Swim figured this would give a little more assurance toward the goal-- hopefully avoiding possible excess loss. However, this amount of salt, being added first created instant precipitation in the boiling glass teapot, thereby indicating an excess of salt, once again, at 20/100 ratio. Solution was then given double the water and cleared up.
As a matter of fact just tested, was a solution after re-x 1 gram rue alkaloids Manske style: 10/100 Salt/Water
Solution was basified yielding absolutely no color change and additional alkaloids.
Caapi alkaloid solution however, after collection of beautiful Yellow Salts, was re-basified and showed classic color change and released what seem to be, at most, an additional 5-10%.
Unfortunately, not having recorded exact weights, an exact figure will not be available for this experiment.
Nevertheless, the conclusion is that there is some trouble when attempting Manske of Caapi.
Not to mention the large needles, characteristic of Rue Harmala Salts (harmaline?) were not present in the Caapi salt precipitation.
And, guessing due to the salted water and very small crystal formation, precipitates were a bit harder to collect that the standard Manske on Syrian Rue.
I'm going to try one more time; and if loss seems excessive enough to indicate-- especially-- non precipitating THH, then this approach will be discarded in favor of some kind of re-acidification and evaporation to yield the desired Caapi Harmala Salts for tincture making.
