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.
