Integrated evaluation of malonyl ginsenosides, amino acids and polysaccharides in fresh and processed ginseng

- Malonyl-ginsenosides in ginseng products were characterized by LC-Q-TOF/MS.
- Twelve malonyl ginsenosides were rapidly screened by the characterized ions.
- Contents of 17 amino acids and polysaccharides in ginseng products were determined.
- Arginine, glutamic acid, and aspartic acid were abundant in ginseng products.
- Optimal time for the accumulation of ingredients was suggested to be 5-6 years.
