Four new triterpenois saponins named kalopanax-saponins C (4), D (5), E (6) and F (7) were isolated from the roots of Kalopanax septemlobus (THUNB.) KOIDZ. together with three known saponins, kalopanax-saponins A (1) and B (2), and chikusetsusaponin IV (3). On the basis of chemical and spectral data, the structures of these new saponins were elucidated to be as follows : (4), 3-O-α-rhamnopyranosyl-(1→2)-[β-glucopyranosyl-(1→3)]-α-arabinopyranosyl hederagenin 28-O-α-rhamnopyranosyl-(1→4)-β-glucopyranosyl-(1→6)-β-glucopyranosyl ester; (5), 3-O-α-rhamno-pyranosyl-(1→2)-[β-glucopyranosyl-(1→3)]-α-arabinopyranosyl oleanolic acid 28-O-α-rhamnopyranosyl-(1→4)-β-glucopyranosyl-(1→6)-β-glucopyranosyl ester; (6), 3-O-β-glucopyranosyl-(1→3)-β-glucuronopyranosyl oleanolic acid; (7), 3-O-α-arabinopyranosyl-(1→2)-[β-glucopyranosyl-(1→3)]β-glucuronopyranosyl oleanolic acid 28-O-β-glucopyranosyl ester.
