Saponin from zygophyllum album and biological investigation

ABSTRACT

The aerial parts of the Zygophyllum album L. afforded nine glycosidal saponins of quinovic, oleanolic, ursolic acid and unidentified sapogenin. They identified by mass spectrometry and by co- chromatography. Their sugar moieties were identified as glucose, xylose, rhamnose and glucuronic acid by GLC and paper chromatography. The presence of the glycosides of oleanolic and ursolic is considered to be the first record in Zygophyllum album. The crude saponin as well as the oleanolic acid showed significant analgesia activity for the first time and some antimicrobial one
