Abstract

From the Cameroonian plant Combretum bracteatum (Laws.) Engl. and Diels a new compound, beta-D-glucopyranosyl 3 beta,19 alpha-dihydroxy-2-oxo-urs-12-en-28-oate, was isolated along with three known ursane and oleane triterpenes and two galactopyranosyl lipids. This represents the first example of a naturally occurring 2-oxo-urs-12-enoic acid derivative.
