摘　　要：A nonasaccharide saponin, new hederagenin saponin, had been isolated from the bark of Kalopanax septemlobus (Thunb.) Koidz., and its structure was elucidated by HRESI-MS, NMR experi- ments and chemical analyses as 3-O-β-D-xylopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-rhamno- pyranosyl-(1→2)-α-L-arabinopyranosyl hederagenin 28-O-β-D-xylopyranosyl-(1→3)-β-D–xylopyra- nosyl-(1→2)-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)]-β-D-glucopyranoside.A nonasaccharide saponin, new hederagenin saponin, had been isolated from the bark of Kalopanax septemlobus (Thunb.)
