What caught my curiosity immediately was the casual indifference shown to what is certainly an extraordinary discovery. Here, amongst some 40 or so alkaloids found in each of these two species, there were five amphetamines that had heretofore been thought to be inventions of man. Two of these are Schedule II drugs, Amphetamine and Methamphetamine. Two are Schedule I drugs, N,N-Dimethylamphetamine and 4-Methoxyamphetamine. And the fifth one is a major human metabolite of Amphetamine, 4-Hydroxyamphetamine. To my knowledge, none of these had ever before been reported as being natural plant alkaloids. This unprecedented discovery elicited only a passing line of comment in the earlier of the two papers.
My first thoughts as to origin were directed towards the well known natural hydroxylated amphetamines such as norephedrine, ephedrine and N-methylephedrine. I know that ephedrine and pseudoephedrine, frequent precursors in the illegal synthesis of methamphetamine, can be reduced to methamphetamine as an artifact of analysis. The sample insertion conditions of the gas chromatograph can effect this conversion. But then, there was no mention of any of these hydroxylated alkaloids as being present in either Acacia.
Might a contaminated round-bottomed flask have been purchased at a garage sale outside an abandoned meth-lab and served as the source of these "man-made" compounds? Unlikely, even in Texas.
Even more dramatic, one of these amphetamines, the 4-Methoxyamphetamine, is the increasingly notorious PMA that is appearing as one of the lethal "Ecstasy" offerings in the rave scene.
Several months ago I tried to contact, individually, the two principal authors, by both e-mail and personal snail-mail, and I have received no response as yet.

The total of all psychoactive substances in A. rigidula is appox. 14954 ppm, or 0.015%

Jo, und wenn du 40-prozentigen Wodka, 30-prozentigen Ouzo und 50-prozentigen Absinth zusammenschüttest hast du 120-prozentigen Alkohol. ;)
