Two crystalline components I and II were isolated from the total saponin of Kalopanax septemlobus (Thunb.) koidz. Crystalline II was identified as kalopanax saponin A and I was named as Kalopanax saponin C and eluciated as 3-O-[alpha-L-rhamnopyranosyl-(1----2)-alpha-L-arabinopyranosyl]- hedragenin-28-[alpha-L-rhamnopyranosyl-(1----2)- beta-D-glucopyranosyl (1----6)-beta-D-glucopyransyl]ester on the basis of spectral data (13CNMR, 1HNMR, IR and FAB-MS).
