Two new saponins, bipinnatifidusoside F1(XII) and F2(XIII), were isolated along with eleven known saponins from the dried leaves of Panax japonicus var.bipinnatifidus(Seem.)Wu et Feng collected in the Range of Qinling Mountains in China. By spectrometric analysis(FAB-MS,1H and 13CNMR,1H-1H COSY), their structures were elucidated as dammar-25(26)-ene-3 beta, 12 beta, 20(S),24 zeta-tetraol-(20-O-beta-D-glucopyranosyl)-3-O- beta-D-glucopyranosyl(1-2)-beta-D-glucopyranoside (bipinnatifidusodie F1) and dammar-22(23) ene-3 beta, 12 beta, 20(S),24 zeta-tetraol-(20-O-beta-D-glucopyranosyl)-3-O-beta- D-glucopyranosyl(1-2)-beta-D-glucopyranoside (bipinnatifidusoside F2), respectively. The known saponins were identified as ginsenoside F1,F2,F3,Rg2,Re,Rd,Rb1,Rb3, 24(S)-pseudoginsenoside F11, panasenoside and majoroside F1. Compared with bipinnatifidusoside F2, majoroside F3 was corrected as dammar-22(23)-ene-3 beta, 12 beta,20(S),24 zeta-tetraol-(20-O-beta-D- glucopyranosyl)-3-O-beta-D-glucopyranoside.
