|a Wild ginseng is thought to be superior in its medicinal quality to cultivated ginseng, potentially owing to the differences in active components. This study was designed accordingly to assess the differences in secondary metabolite components and their synthesis in wild and cultivated ginseng by using quantitative proteomics combined with secondary metabolomics approaches. A total of 72 secondary metabolites were found to be differentially abundant, of which dominant abundant in wild ginseng primarily included triterpenoid saponins (ginsenosides) and phytosterols. Ginsenoside diversity was increased in wild ginseng, particularly with respect to rare ginsenosides. Ginsenoside Rk1, F1, Rg5, Rh1, PPT, Rh2, and CK enriched in wild ginseng were validated by HPLC. In addition to ginsenosides, stigmasterol and β-sitosterol were accumulated in wild ginseng. 102 differentially expressed proteins between wild and cultivated ginseng were identified using iTRAQ labeling technique. Among them, 25 were related to secondary metabolism, mainly involved in sesquiterpene and triterpene biosynthesis, which was consistent with metabolomics results. Consistently, the activity levels of HMGR, FDPS, SS, SE, DS, CYP450, GT and CAS, which are key enzymes related to ginsenoside and phytosterol biosynthesis, were confirmed to be elevated in wild ginseng.The biosynthesis of ginsenosides and phytosterols in wild ginseng is higher than that in cultivated ginseng, which may be related to natural growth without artificial domestication. To some extent, this study explained the accumulation of pharmacodynamic components and overall quality of ginseng, which could provide reference for the germplasm improvement and planting of ginseng
