Venalstonine and dioxokopsan derivatives from Kopsia fruticosa.

Toh-Seok Kam1, Yeun-Mun Choo.   

Abstract

Two new venalstonine derivatives, viz., venacarpines A and B, and one new dioxokopsan derivative, kopsorinine, in addition to the kopsifolines A-F, and 11 other known alkaloids, were isolated from a Malayan Kopsia species. The structures of the new alkaloids were determined using NMR and MS analysis.
