Abstract

Two new furostanol glycosides, named tribufurosides I (1) J (2), were isolated from the fruits of Tribulus terrestris L. by a combination of chemical and spectroscopic methods. Its structures were established as 26-O-beta-D-glucopyranosyl-(25S)-5alpha-furost-12-one-2alpha,3beta,22alpha,26-tetraol-3-O-beta-D-glucopyranosyl (1-->2)-beta-d-glucopyranosyl (1-->4)-beta-d-galactopyranoside (1) and 26-O-beta-D-glucopyranosyl-(25R)-5alpha-furost-20(22)-en-12-one-2alpha,3beta,26-triol-3-O-beta-D-glucopyranosyl (1-->4)-beta-D-galactopyranoside (2).
