Abstract

A new triterpenoid saponin named bredemeyeroside B has been isolated from the roots of Bredemeyera floribunda and its structure elucidated as 3-O-beta-D-glucopyranosyl-2 beta,3 beta,27-trihydroxyolean-1 2-en-23,28-dioic acid 28-O-beta-D-xylopyranosyl-(1 hamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1 -->3]-beta-D-fucopyranoside by means of MS, NMR and chemical evidence. In addition rutin was also isolated. In laboratory tests bredemeyeroside B showed snake venom antidote activity.
