چکیده

The known furostanol saponins methylprotodioscin and protodioscin and two new sulfated saponins, sodium salt of 26-O-beta-glucopyranosyl-22alpha-methoxy-(25R)-furost-5-ene-3beta,26-diol-3-O-alpha-rhamnopyranosyl-(1-->2)-beta-4-O-sulfo-glucopyranoside (methylprototribestin) and sodium salt of 26-O-beta-glucopyranosyl-22alpha-hydroxy-(25R)-furost-5-ene-3beta,26-diol-3-O-alpha-rhamnopyranosyl-(1-->2)-beta-4-O-sulfo-glucopyranoside (prototribestin) have been isolated from the aerial parts of Tribulus terrestris L. growing in Bulgaria. The structures of the new compounds were elucidated on the basis of 1D and 2D (DQF-COSY, TOCSY, HSQC-TOCSY, HSQC, HMBC, ROESY) NMR data, ESI mass spectra and chemical transformation.

Aphrodisiac & Tonic Activity of Tribulus Leaf

Tribulus terrestris is a prostrate spreading herb, the fruit of which contains sharp, rigid spines and for this reason it is known as puncture vine. It is native to many geographical zones, including the Mediterranean regions, India, China, Africa and Australia. In the 1990s attention focused on the Bulgarian research of a standardised extract of Tribulus leaf (TLSE, standardised to not less th...
