Zusammenfassung: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.
