Analysis of over-the-counter analgesics purported to contain mescaline from the peyote cactus (Lophophora williamsii: Cactaceae)

Journal of the Botanical Research Institute of Texas July 23, 2021 Robert Jean Leblanc, Sohan de Silva, Martin Terry 2 citations

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...

Correlation of mescaline concentrations in Lophophora williamsii (Cactaceae) with rib numbers and diameter of crown (U.S.A.)

Journal of the Botanical Research Institute of Texas July 15, 2020 R. Newbold, Sohan de Silva, Martin Terry 1 citation

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...

Regulation of peyote (Lophophora williamsii: Cactaceae) in the U.S.A: A historical victory of religion and politics over science and medicine

Journal of the Botanical Research Institute of Texas July 24, 2017 Martin Terry, Keeper Trout 11 citations

The peyote cactus, Lophophora williamsii, is presently classified as a Schedule 1 Controlled Substance in the USA, with an exemption for use as a sacrament in bona fide religious ceremonies of the Native American Church (NAC). Any botanist or other researcher seeking to work with peyote or any of its alkaloids, must com-ply with applicable (nontrivial) regulatory requirements. This paper...

Mescaline Concentrations in Three Principal Tissues ofLophophora williamsii(Cactaceae): Implications for Sustainable Harvesting Practices

Haseltonia February 1, 2015 Molly T. Klein, Md Abul Kalam, Keeper Trout et al. 12 citations

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...

New mescaline concentrations from 14 taxa/cultivars of Echinopsis spp. (Cactaceae) (“San Pedro”) and their relevance to shamanic practice

Journal of Ethnopharmacology July 15, 2010 Olabode Ogunbodede, Douglas Mccombs, Keeper Trout et al. 54 citations

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...
