A new lupane triterpenoid saponin, 3, 11-dihydroxy-lupan-20-en-28-oic acid 28-o-$\alpha$-L-rhamnopyranosyl-(1$\rightarrow$4)-$\beta$-D-glucopyranosyl-(1$\rightarrow$6)-B-D-glucopyranosyl ester, have been isolated from the leaves of Acanthopanax koreanum Nakai (Araliaceae) together with one known flavonol glycoside, rutin. The structure were elucidated on the basis of spectral and chemical evidence.
