Abstract
Ginseng (Panax ginseng C.A.Meyer.) is an important agricultural heritage. Mountain cultivated ginseng (MCG) is a popular health product in the market, the chemical composition of MCG can be influenced by the growth of years. Thus, this research analysed MCG samples grown for 5–25 years. Total ginsenosides and polysaccharides were measured spectrophotometrically, then metabolomics-based UPLC-Q-TOF-MS and UPLC-MS/MS methods were applied to evaluate the differences in chemical composition. The variation in chemical profiling of MCG from 15 to 25 years was not obvious, while total ginsenosides and polysaccharides were accumulated at the grown age of 15 and 25 year, respectively. The trends of most identified ginsenosides were similar to that of total ginsenosides. The accumulation of amino acids decreased from 5 to 10 years, after that it increased firstly and then decreased. The present study indicated that fifteen years represented maturity and a turning point in MCG growth. Considering the difference in both ginsenosides and polysaccharides over different years of MCG growth, MCG should be rationally harvested to obtain the maximum benefits of industrialization.
