摘要

A new glucoside of hederagenic acid, hederagenic acid-28-O-尾-D-glucopyranoside, together with two known triterpenoids and six known triterpenoid saponins, was isolated from the roots of Kalopanax septemlobus (Thunb.) Koidz. Their structures were identified as hederagenic acid-28-O-尾-D-glucopyranoside (1), hederagenic acid (2), hederagenin (3), hederagenin-28-O-尾-D-glucopyranoside (4), 尾-hederin (5), kalopanaxsaponin A (6), 3-O-伪-L-arabinopyranosyl-arjunolic acid-28-O-伪-L-rhamnopyranosyl-(1鈫?)-O-尾-D-glucopyranosyl-(1鈫?)-O-尾-D-gluco pyranoside (7), kalopanaxsaponin B (8) and kalopanaxsaponin H (9) on the basis of spectroscopic analysis and chemical properties.
