My friend got about 300 mg of a goopy, brown substance after the first vinegar pull.  The second time, she got about 500 mg of white waxy crystal substance (after second vinegar treatment of the same limonene), much whiter than the tannish crystal she'd gotten from  a prior extraction.  Both taste bitter, I am told.  One presumes that both are active.

Is the brown goop a collection of alkaloids other than mescaline, and the white second draw  a more pure mescaline draw?  Or does this just sometimes happen,and we can presume that both substances are a collection of alkaloids, both mostly mescaline?
