Very nice work guys!
Endlesness, given that you have very pure harmalas at hand ,could you please have at look at the following:
Try dissolvinng small amount of harmine, harmaline and ,harmine + harmaline (lets say 100 mg,100 mg and 50+50 mg respecively) in Alcohol in different test tubes ,let for a day or so in room temperature and evaporate them seperately.
As you can imagine this could be a test on "Harmala red" ,from which compound it forms and if indeed its a harmine/harmaline reaction byproduct or if its something else in the plant turning into harmala red. I think more or less such a test will be conclusive on whats happening, even better if somehow one could get the samples analysed afterwards. The reason i am proposing a retest on "common knowledge" about harmalas, is that a) in Merck index harmala alkaloids are said to recrystalise from alcohol so if they reacted they wouldnt propose it as a re-x solvent, b) whiterasta's methods utilise alcohol and still no problems appear as far as activity goes ,c) i have seen people doing multiple alcohol (ethyl alcohol) washes/solutions of crude harmala alkaloids and they retain activity.
Hmmmm any feedback on such ideas? The material Endlessness and others have presented that is a bit off white seems premium for such experiments.
