Résumé
The sterol constituents of senita cactus Lopho- cereus schottii were investigated. In addition to lophe- nol and schottenol, six new sterols were identified in this plant : cholest-7-en-3^-ol, campest-7-en-3y^-ol, choles ta-8, l4-dien-3|/j>-cl, stigmasta-7* 22-dien-3^j>-ol, 24-methylenelophenol and locereol, a new phytosterol of the structure 4Q<-inethyl-cholesta-8, l4-dien-3^-ol. A possible pathway for senita sterol biosynthesis is pre sented and the relationship between senita cactus and the fruit fly Drosophila pachea is discussed.
