The ginsenoside was analyzed by High performance liquid chromatography mass spectrometry detector(HPLC/MS) for evaluated ginsenoside composition characteristics and content diversity in wild gineng and the ginseng cultivated in forests.Results showed that the ginsenoside Re,Rg1,Ro,Rf,Rg2,Rb1,Rc,Rb2 and Rd were detected in different source ginseng,notoginsenoside R1,R2,R3 and propylene acyl ginseng saponins Rb1,Rc were detected in wild ginseng in the same time,by contrast,propylene acyl ginseng saponins Rb1,Rc and Rd were detected exclusively in wild ginseng under forest and no notoginsenoside R1 and R3.The ginsenoside contents of Rg1,Ro,Rf,Rg2,Rb1,Rc,Rb2 and Rd were similar except Re in wild ginseng and the ginseng cultivated in forest,s ginsenoside Re content in the ginseng cultivated in forests was higher than that of the wild ginseng and the difference was significant in the P0.01 level,the average value was 5.042mg/g.
