Vachellia rigidula
Vachellia rigidula, commonly known as blackbrush acacia or chaparro prieto, and also known as Acacia rigidula, is a species of shrub or small tree in the legume family, Fabaceae. Its native range stretches from Texas in the United States south to central Mexico. This perennial is not listed as being threatened. It reaches a height of. Blackbrush acacia grows on limestone hillsides and canyons.
Phytochemistry
A phytochemical study of V. rigidula 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 of several phenolic amines that had previously been found by the same research group in the related species Senegalia berlandieri, but which otherwise are known only as products of laboratory synthesis. Compounds found in the highest concentrations were phenethylamine, tryptamine, tyramine, and β-Methylphenethylamine. Other notable compounds reported were N,''N''-dimethyltryptamine, mescaline, and nicotine, although these were found in low concentrations.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.
Uses
Vachellia rigidula is used in weight loss dietary supplements because of the presence of chemical compounds claimed to stimulate beta-receptors to increase lipolysis and metabolic rate and decrease appetite.Vachellia rigidula is also known as a large honey producer and early blooming plant for its native region.
