| Abstract: | Two new furostanol glycoside, 26-O-β-D-glucopyranosyl-(25S)-5α-furost-3β,22α,26-triol-3-O-β-D- rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)]-β-D-galactopyranoside (1) and 26-O-β-D-glucopyranosyl- (25S)-5α-furost-20(22)-en-2α,3β,26–triol-3-O-β-D-glucopyranosyl-(1→2)-O-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (2) were isolated from the fruits of Tribulus terrestris L.. The structures of two new furostanol saponins were elucidated by spectroscopic methods. |
