The purpose of this study was to investigate samples of commercial over-the-counter products purported to contain extracts from peyote cactus (Lophophora williamsii), a vulnerable species. Samples were extracted with organic solvent and then washed to remove impurities. The extracts of these products were subjected to an analysis by real-time mass spectrometry (DART-MS) to determine the...

Lophophora williamsii, peyote, is a small cactus growing to approximately 10 cm in diameter with a flat to dome-shaped spineless crown with fissures or ribs that develop following the Fibonacci series and whose numbers indicate relative degree of maturing. In this study crown tissue of 30 wild-collected specimens was analyzed to determine whether there was a correlation between the...

We evaluated the pharmacological consequences of tissues other than crown being included with harvested peyote. Mean mescaline concentrations were determined for crown, non-chlorophyllous stem, and root, using mature individuals from the same population in South Texas. Samples of each tissue—crown, non-chlorophyllous stem, and root—were taken from each of 13 individual plants. Samples were...

Aim of the studyThe aim of the present study is to determine in a procedurally uniform manner the mescaline concentrations in stem tissue of 14 taxa/cultivars of the subgenus Trichocereus of the genus Echinopsis (Cactaceae) and to evaluate the relationship (if any) between mescaline concentration and actual shamanic use of these plants.Materials and methodsColumnar cacti of the genus...
