Gad vide om vi med tiden kommer til at opdage flere "syntetiske" stoffer i naturen. Mon ikke

mindes også at amfetamin blev fundet et eller andet random sted i amazon for nogle år tilbage... Fedt når det sker

A phytochemical study of A. rigidula[6] by workers at the Texas A & M University Agricultural Research and Extension Center at Uvalde, TX, reported the presence of over forty alkaloids, including low amounts (up to ~ 15 ppm) of several amphetamines that had previously been found by the same research group in the related species A. berlandieri,[7] but which otherwise are known only as products of laboratory synthesis. Compounds found in the highest concentrations (ranging from a few hundred to a few thousand ppm) were phenethylamine, N-methylphenethylamine, tyramine and N-methyltyramine. Other notable compounds reported were N,N-dimethyltryptamine, mescaline, and nicotine, although these were found in low concentrations (e.g. mescaline at 3-28 ppm).

The presence of such an unprecedented chemical range of psychoactive compounds, including ones not previously found in nature, in a single plant species has led to the suggestion that some of these findings may have resulted from cross-contamination or were possibly artifacts of the analytical technique.[8]

A. berlandieri contains a number of diverse alkaloids, the most plentiful of which are N-methylphenethylamine, tyramine, and phenethylamine.[3] The total alkaloid content in dried leaves has been reported to be in the range 0.28-0.66%.[6] In a recent study, researchers identified thirty-one alkaloids in samples of plant foliage, including trace amounts of four amphetamines previously known only from laboratory synthesis: amphetamine, methamphetamine, para-hydroxyamphetamine and para-methoxyamphetamine. Other trace alkaloids include nicotine, and mescaline (found in many cacti but infrequently in other plants).[3] The same group of researchers later reported finding most of the same alkaloids in A. rigidula, a related species also native to the Southwestern U.S.[7] There are no reports in the literature of these findings having been repeated, however, leading to the suggestion that they resulted from cross-contamination or were possibly artifacts of the analytical technique.[8]

Synes især det er fedt at de har lagt vægt på at få fastllagt at tramadol'en er biosyntetiseret og ikke bare en kontamination, som det desværre lod til at være tilfældet med A. Berlandieri & A. Rigidula.

Caesulia axillaris skulle også indeholde amfetamin og andre alkaloider.
