ABSTRACT
OBJECTIVE: To investigate the proportion of 8 kinds of ginsenoside to ginsenoside Rg1 in Panax ginseng and the regularity of growth year in Jilin province, and to provide reference for the identification of growth year. METHODS: The samples of garden ginseng, wild-cultivated ginseng and wild ginseng were collected from different growth years (3-30 years) in Jilin province. The contents of 8 ginsenoside (ginsenoside Rg1, Re, Rf, Rb1, Rc, Rb2, Rb3, Rd) in P. ginseng were determined by HPLC. The contents of saponins as well as the proportion of 8 kinds of ginsenoside to ginsenoside Rg1 were calculated; the relationship of the proportion with growth year was investigated. RESULTS: As the increase of growth year, the proportion of 8 kinds of ginsenosides in garden ginseng to ginsenoside Rg1 as well as that of ginsenoside Re, Rb1, Rc, Rd to ginsenoside Rg1 were decreased gradally (P<0.001); the proportion of ginsenoside Re to ginsenoside Rg1 in wild-cultivated ginseng decreased first and then increased(P<0.001); the proportion of 8 kinds of ginsenosides to ginsenoside Rg1 as well as the proportion of ginsenoside Re and Rb1 to ginsenoside Rg1 were increased gradually in wild ginseng (P<0.001); the proportion of ginsenoside Rf, Rb3 to ginsenoside Rg1 in garden ginseng, wild-cultivated ginseng and wild ginseng had no significant difference(P>0.05). CONCLUSIONS: Garden ginseng, wild-cultivated ginseng and wild ginseng contain 8 kinds of ginsenosides. The growth year can be predicted preliminarily according to the proportion of ginsenoside Rg1 and ginsenoside Re, Rb1 to ginsenoside Rg1.
