Two new saponins were isolated from the leaves of Ilex psammophila. Their structure was established by chemical and spectroscopic methods as 28-O-beta-D-glucopyranosylester of 20(S)-ilexgenin A ([structure: see text]) and 28-O-beta-D-glucopyranosylester of 20(S)-3beta,19alpha,24-trihydroxyurs-12-ene-23, 28-dioic acid ([structure: see text]).
