Abstract

The phytochemical investigation of the aerial parts of Tribulus terrestris of Bulgarian origin has resulted in the isolation of the novel furostanol saponin, named tribol, together with two known spirostanol saponins and sitosterol glucoside. The structure of tribol was determined as(25R)-furost-5(6)-ene-3β,16,26-triol- 3-O-&alpha-rhamnopyranosyl-(1-->2)-[α-rhamnopyranosyl- (1-->4)]-β-glucopyranoside by spectral analysis, including extensive 1D and 2D-NMR experiments.
