SAPONINS FROM ZYGOPHYLLUM ALBUM L.

Abstract
Four saponins were isolated from the overground parts of Z. album L. along with b-sitosterol-b-D-glucopyranoside. Their structures were identified as 14-decarboxyquinovic acid-0-(3®1)-a-L-rhamnopyranoside (1), quinovic acid-(28®1)-a-L-rhamnopyranosyl ester (2), which is new; quinovic acid-o-(3®1)-a-L-rhamnopyranoside (3) and quinovic acid-o-(3®1)-b-D-rhamnopyranoside (4). This identification was based on chemical studies. Glc, Gc/Ms and Mass spectral analysis.
