Abstract: | New triterpene glycosides have been isolated from the berries of Crimean ivyHedera taurica Carr. (family Araliaceae) — hederoside A1 (methyl ester of 3-O- -D-glucopyranosylhederagenin) and hederoside D1 3-O-O- -D-glucopyranosyl]-(1 2)- -D-glucopyranosyl]hederagenin and also the known glycosides 3-O- -D-glucopyranosyloleanolic acid and 3-O-O- -D-glucopyranosyl-(1 2)- -L-arabinopyranosyl]hederagenin. The structures of these compounds were established on the basis of the results of chemical methods and1H and13C NMR spectroscopy.M. V. Frunze Simferopol' State University.
