Oleanane and taraxerane glycosides from the roots of Gomphrena macrocephala.
    Journal of natural products, 2006, Volume: 69, Issue:11

    Phytochemical screening of the roots of Gomphrena macrocephala, with particular attention to its triterpene glycoside constituents, has resulted in the isolation of two new oleanane glycosides (1 and 2) and a new taraxerane glycoside (3). The structures of 1-3 were determined as 11alpha,12alpha-epoxy-3beta-[(O-beta-D-glucuronopyranosyl)oxy]olean-28,13-olide (1), 11alpha,12alpha-epoxy-3beta-[(O-beta-D-galactopyranosyl-(1-->3)-O-[beta-D-glucopyranosyl-(1-->2)]-beta-D-glucuronopyranosyl)-oxy]olean-28,13-olide (2), and 11alpha,12alpha-epoxy-3beta-[(O-beta-D-glucuronopyranosyl)oxy]taraxer-14-en-28-oic acid beta-D-glucopyranosyl ester (3), respectively, on the basis of their spectroscopic data and the results of hydrolysis. The aglycones (1a and 3a) of 1-3 with an epoxy group showed cytotoxic activity against HSC-2 human oral squamous carcinoma cells.
