Abstract:

Two new furostanol glucosides, named tribufurosides G and H, were isolated from Tribulus terrestris L. The structures of the two new furostanol glucosides were elucidated as 26-O-β-D-glucopyranosyl-(25R)-5α-furost-12-one-3β,22α,26-tetraol-3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside(1) and 26-O-β-D-glucopyranosyl-(25S)-5α-12-one-2α,3β,22α,26-tetraol-3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyra-nosyl-(1→4)-β-D-galactopyranoside(2) by 1D, 2D NMR techniques, ESI-MS analysis as well as chemical methods.

Key words: Tribulus terrestris L.; Furostanol saponin; Tribufurosides G and H
