Abstract
Two new steroid saponins, named terrestrinins A (1) and B (2), along with six known compounds were isolated from the Chinese medicine herb Tribulus terrestris, and their chemical structures were elucidated as 26-O-β-D-glucopyranosyl-(25S)-furostan-4(5),20(22)-diene-3,12-dione (1) and 26-O-β-D-glucopyranosyl-(25S)-5α-furostane-3β,22α,26-triol-3-O-β-D-xylopyranosyl(1→3)-[(β-D-xylopyranosyl(1→2)]-β-D-glucopyranosyl(1→4)-[α-L-rhamnopyranosyl(1→2)]-β-D-galactopyranoside (2) on the basis of spectroscopic techniques.
