Traditional Chinese Medicine “jili”(Tribulus Terrestris L.) is the important medicine used to treat cardiovascular diseases. A new furosteroidal saponin, together with a known steroidal saponins, were isolated from the fruits of T. Terrestris L The structure of the new furosteroidal saponin, named Tribuluside A, was elucidated as 26-O-β-D-glucopyranosyl-(25R)-5α-furost-3β, 22α,26-triol-3-O-[β-D-Xylopyranosyl(1→3)]-[β-D-xylopyranosyl(1→2)]-β-D-glucopyranosyl(1→4)-[α-L- rhamnopyranosyl(1→2)]-β-D-galactopyranoside mainly by using 1D, 2D NMR techniques, ESI-MS analysis as well as chemical methods.
