Triterpenoidal saponins from Cornulaca monacantha.
From the aerial parts of Cornulaca monacantha, three new triterpenoidal saponins have been isolated and their genuine structures were identified as 3-O-[beta-xylopyranosyl-(1-->3)-beta- glucuronopyranosyl]-30-methylphytolaccagenate (2), 3-O-[beta-xylopyranosyl- (1-->3)-beta-glucuronopyranosyl]-30-methylphytolaccagenate 28-O-beta-gluco-pyranoside (3) and 3-O-[beta-xylopyranosyl-(1-->3)-beta- glucurono-pyranosyl]-30-methylserjanate 28-O-beta glucopyranoside (4) together with nine known saponins of oleanolic acid (5-9), hederagenin (1, 10, 11) and 30-methyl phytolaccagenate (12).
