title: Cactus alkaloids. XXXI. beta-Phenethylamines and tetrahydroisoquinolines from the Mexican cactus dolichothele uberiformis.
abstract: A total of ten alkaloids have been identified in extracts of a Mexican cactus, Dolichothele uberiformis (Zucc.) Br. and R. The data provide documentation for the presence of (--)-synephrine, (--)-longimammine, N-methyl-3,4-dimethoxy-beta-phenethylamine, N-methyl-4-methoxy-beta-phenethylamine, (--y-normacromerine, N-methyltryramine, hordenine, longimammatine, and the first reported isolation of (--)-N,N-dimethyl-beta-hydroxy-beta-phenethylamine (ubine) from a natural source. Spectral data support the identification of another new alkaloid (uberine) as 5-methoxy-7-hydroxy-2-methyl-1,2,3,4-tetrahydroisoquinoline.
