Abstract

Three new steroidal saponins were isolated from the fruits of Tribulus terrestris, and their structures were elucidated as (25R,S)-5α-spirostane-12-one-3β-ol-3-O-β-xylopyranosyl(1→2)-[β-xylopyranosyl(1→3)]-β-glucopyranosyl(1→4)-[α-rhamnopyranosyl(1→2)]-β-galactopyranoside; 26-O-β-glucopyranosyl-(25S)-5α-furostane-12-one-3β,22α,26-triol-3-O-β-glucopyranosyl(1→2)-β-galactopyranoside; 26-O-β-glucopyranosyl-(25S)-5α-furostane-12-one-3β,22α,26-triol-3-O-β-glucopyranosyl(1→4)-[α-rhamnopyranosyl(1→2)]-β-galactopyranoside, respectively, by spectroscopic analysis and color reaction.
