Two new steroidal saponins were isolated from the fruits of Tribulus terrestris L. Their structures were elucidated by spectroscopic and chemical analysis as (23S,24R,25R)-5alpha-spirostane-3beta,23,24-triol-3-O-{alpha-L-rhamnopyranosyl-(1 --> 2)-[beta-D-glucopyranosyl-(1 --> 4)]-beta-D-galactopyranoside} (1) and (23S,24R,25S)-5alpha-spirostane-3beta,23,24-triol-3-O-{alpha-L-rhamnopyranosyl-(1 --> 2)-[beta-D-glucopyranosyl-(1 --> 4)]-beta-D-galactopyranoside} (2).
