title: Furostanol saponins from the fruits of Tribulus terrestris.
abstract: Two new steroidal saponins were isolated from the fruits of Tribulus terrestris. Their structures were assigned by spectroscopic analysis and colour reaction as 26-O-β-D-glucopyranosyl-(25R)-5α-furostane-12-one-3β,22α,26-triol-3-O-β-D-glucopyranosyl(1 → 4)-β-D-galactopyranoside (1); 26-O-β- D-glucopyranosyl-25(R)-5α-furostan-12-one-3β,22α,26-triol-3-O-α-L-rhamnopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 4)]-β-D-galactopyranoside (2).
