One new triterpenoidal saponin, saponin F(2) has been isolated from the bark of Kalopanax pictum Nakai var. typicum (Araliaceae), together with one known saponin, kizuta saponin $K_{12}$ (1). On the basis of chemico-spectral evidences, the structure of 2 has been elucidated to be 3-O-${\beta}$-D-xylopyranosyl$(1{\rightarrow}3)$-${\alpha}$-L-rhamnopyranosyl$(1{\rightarrow}2)$-${\alpha}$-L-arabinopyranosyl-23-hydroxyolean-12-en-28-O-${\alpha}$-L-rhamnopyranosyl$(1{\rightarrow}4)$-${\beta}$-D-glucopyranosyl$(1{\rightarrow}6)$-${\beta}$-D-glucopyranosyl ester.

Liriodendrin, m. p. $269-270^{\circ}$, $C_{22}$ $H_{46}$ $O_8$ as one of the antihypertensive components was obtained from the cortex of Kalopanax pictum. Acid hydrolysis of liriodendrin yielided liriresinol-A, -B and glucose. The stereochemistry of liriodendrin was established by the NMR spectrum of liriodrin octaacelate. The NMR spectrum of liriodendrin octaacetate showed that $di-{\beta}-glucoside$ of lirioresinol-B type occurs in nature.

Hederine, m. p. $256{\sim}257^{\circ}\;C_{41}H_{64}O_{11}\;{\cdot}\;2H_{2}O$ : $23-hydroxy-3{\beta}-({\beta}-{\alpha}-arabinosidor hamnoside)-olenana-12-ene-oique,$ was obtained from the cortex of Kalopanax pictum. Acid hydrolysis of hederine yielded hederagenin, arabinose and rhamnose. Hederagenin was identified by comparison of it's mixed melting point and IR spectra against authentic sample. Arabinose and rhamnose were identified by TLC against standards.
