Two new lupane-triterpene carboxylic acids, called acantrifoic acid A (1) and acantrifoside C (2) have been isolated from the leaves of Acanthopanax trifoliatus. Based on extensive 1D and 2D NMR spectroscopic data, their chemical structures were determined as 3alpha-acetoxy-30-hydroxylup-20(29)-ene-23,28-dioic acid and 3alpha-acetoxy-30-hydroxylup-20(29)-ene-23,28-dioic acid 28-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester.
