我们曾从三七(Panax notoginseng(Burk.)F.H.Chen)根分离到人参二醇和人参三醇,并用称量法和薄层层析法对国产人参属植物的三萜皂甙成分进行比较,讨论了达马烷型皂甙与齐墩果烷型皂甙成分的组成和人参属植物系统分类及地理分布的关系。1979年以来,我们又进而研究云南产各种人参属植物三萜皂甙的分离和结构鉴定,已报告的有三七根,芦头(即剪口),花,叶和果;珠子参(P.japonicus C.A.Meyer var.ma- We have isolated Panax notoginseng (Burk.) FHChen root from Panax notoginseng (Burk.) FHChen) and compared the triterpenoid saponin components of domestically produced Panax species by weighing method and thin layer chromatography. The composition of damastan-type saponin and oleanane-type saponin, and the relationship between the classification and geographical distribution of Panax species. Since 1979, we have further studied the isolation and structural identification of triterpenoid saponins produced in Yunnan Province, and have reported the roots of Sanqi, Lutou (ie, clipping), flowers, leaves and fruit; .japonicus CAMeyer var.ma-
