Hordenine, anhalidine, pellotine, 3-demethyltrichocereine, mescaline, dimethoxy-beta-phenethylamine, and the N-monomethyl derivatives of mescaline d 3,4-dimethoxy-beta-phenethylamine have been isolated or identified, or both, in caloid extracts of a Mexican "peyote" cactus, Pelecyphora aselliformis tenberg. This is the first report of the occurrence of some of these alkaloids, including mescaline, in a North American cactus other than Lophophora.
