摘　　要：前已报道秦岭产珠子参(Panax japonicus var.mojor (Burk.) Wu et Feng)叶的九个达玛烷型皂甙成分。本文继续报告得自珠子参叶的另外两个新的同类皂甙成分。珠子参甙F_σ(Ⅰ) 由甲醇中得白色粉末,分子式:C_(48)H_(82)O_(19);正、反相薄层层析示为单一斑点;PPC检查Ⅰ的酸水解物中有葡萄糖和鼠李糖存在:FAB-MS给出分子离子峰m/z 985 (M+Na)^+及碎片峰716(M-162-2H_2O+2H)^+,619(M-162-146-2H_2O+H)^+,439(M-2×162-146-3H_2O+2H)^+,说明Ⅰ中含有二个葡萄糖和一个鼠李糖。In continuation of our studies on the leaves of Panax japonicus vat. major (Burk.) Wu et Feng, two new dammarane saponins are isolated.By means of FAB-MS and ^(13)CNMR, their structures were elucidated as dammar-22(23)-ene-3β,6α, 12β,20(S) ,24§-pentaol- (20-O-β-D-glucopyranosyl)-6-O-α-L-rhamnopyranosyl(1-2)-β-D-glucopyranoside (majorosids F_5) and dammar-23(24)-ene-3β ,6α, 12β,20(S),25-pentaol-(20-O-β-D-glucopyranosyl)-6-O-α-L-rhamnopyranosyl(1-2)-β-D-glucopyranoside (majoroside F_6).
