由于人参(Panax ginseng C.A.Mayer)的天然资源迅速减少,人工栽培又极为困难,因而致力于寻找人参的代用品。苏联学者从人参根中分得六种人参皂甙(Panaxoside)即人参皂甙 A～F。日本学者则通过硅胶薄层层析分离得八种甙(Ginsenoside),同时证明了原人参二醇(Protopanaxadiol)经酸水解后可得人参二醇(Panaxadiol)。此外尚有人从五加皮属刺五加(Eleutherococcus senticosus Maxi-
Since the natural resources of Panax ginseng C.A. Mayer are rapidly reduced and artificial cultivation is extremely difficult, they are dedicated to searching for substitutes for ginseng. Soviet scholars divided six ginsenosides (Panaxside), ginseng saponins A-F from ginseng roots. Japanese scholars isolated eight kinds of ginsenosides by thin-layer chromatography on silica gel, and proved that Panaxadiol can be obtained after acid hydrolysis of protopanaxadiol. In addition, there are still people from the Acanthopanax senticosus (Eleutherococcus senticosus Maxi-
