Abstract: Panax ginseng has been used as a highly valued medicinal plant. To investigate the biochemical variables of mountain cultivated
ginseng roots with different growth periods, five kinds of enzyme activities were measured, respectively. It was found that five
enzyme activities were increased remarkably during the slow-growth period relative to the fast-growth period. The activities of
AMY and ACP were significantly increased during the whole ginseng growth period. However, EST, ALP, CAT activities were
not found changes during the slow-growth period. Enzymatic activities of AMY and ACP can be used as one of the intrinsic
indicators to assess the quality of ginseng and identify the growth period of P. ginseng in the future.

Key words: Panax ginseng, enzyme activity, growth period
