Abstract:

The quality of American ginseng during storage under simulated ecological conditions was evaluated by
examining the changes in active ingredients. The results showed that total saponins, protopanaxatriol Rg1 and Re of
American ginseng were reduced by 0.08%, 0.02%, 0.03%, respectively, while Rb1 was increased by 0.06% after 180 d of
storage. Additionally, total sugar and polysaccharide were decreased by 16.14% and 1.97%, respectively. The content of
amino acids was increased by 0.66%. These observed changes may not attenuate the efficacy of American ginseng.

Key words: American ginseng, keeping fresh, active ingredient, change
