Abstract

Two saponins and a sapogenin were isolated from the leaves of Ilex brevicuspis. Their structures were established by means of spectroscopic methods as brevicuspisaponin 1 (3-O-alpha-L-arabinopyranosyl-20(S)-19 alpha,24-dihydroxyursolic acid), brevicuspisaponin 2 (3-O-alpha-L-arabinopyranosyl-20(S)-19 alpha,23,24-trihydroxyursolic acid) and 23-methylester of 20(S)-3 beta,19 alpha,24-trihydroxyurs-12-en-23,28-dioic acid.
