加拿大产西洋参茎叶的化学研究（Ⅰ）十一种三萜皂苷的分离与鉴定王金辉１）李铣（沈阳药科大学天然药物研究室，沈阳１１００１５）用大孔树脂，硅胶柱色谱及ＨＰＬＣ反相柱色谱法从加拿大产西洋参（Ｐａｎａｘｑｕｉｎｑｕｅｆｏｌｉ－ｕｍＬ．）的茎叶中分离得到１１种...

From leaves and stems of Panax quinquefolium L.from Canada, 11 triterpenoid saponins were isolated. The structures of these saponins have been identified as ginsenoside Rg1(1),Re(2),Rd(3),Rc(4),Rb3(5),Rb2(6),Rb1(7),pseudo ginsenoside F11(8),majoroside F1(9),gypenoside Ⅸ(10)andⅩⅦ(11).Among them,coumponds(9)and (10)were isolated from this plant for the first time.
