One new triterpenoidal bisdesmoside, saponin C (3) were isolated from the leaves of Kalopanax pictum var. chinense along with two known saponins, saponin B (2, sapindoside C) and saponin A (1, sapoindoside B). On the basis of chemical and spectral evidences, the structure of a new triterpenoidal saponin has been elucidated to be 3-O-$\beta$-D-glucopyranosyl (1$\rightarrow$4)$\beta$-D-xylopyranosyl (1$\rightarrow$3)-$\alpha$-L-rhamnopyranosyl (1$\rightarrow$2)-$\alpha$-L-arabino-pyranosyl-23-hydroxyolean-12-en-28-O-$\alpha$-L-rhamnopyrano syl (1$\rightarrow$4)-$\beta$-D-glucopyranosyl (1$\rightarrow$6)-$\beta$-D-glucopyranosyl ester.
