Abstract
Two new lupane-triterpene glycosides named acankoreosides C and D, were iso lated from the leaves of Acanthopanax koreanum. Based on spectroscopic data , the chemical structures were determined as 3-O-beta-D-glucopyranosyl 3 al pha,11 alpha-dihydroxylup-20(29)-en-28-oic acid 28-O-alpha-L-rhamnopyranosy l-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester and 3 a lpha,11 alpha-dihydroxylup-23-al-20(29)-en-28-oic acid 28-O-alpha-L-rhamnop yranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester, respectively.
