Objective: To observe the anti-fatigue effects of ginseng and its processed products. Method: One hydred and twenty mice were allocated randomly into ginseng

red ginseng and red ginseng processed by high pressure groups. Each treatment was divided into three subgroups by dosages(5

2.5

1.25 g·kg-1). Blank control group was treated with 0.9%NaCl. Drugs were administered to mice for 15 days

then fatigue-related biochemical indicators were analyzed. Result: Compared with the control group

the mice of ginseng group had a higher content of liver glycogen(11.33±3.45)g·kg-1(P<0.01)and muscle glycogen(1.98±0.83)g·kg-1(P<0.05)

and lower content of blood urea nitrogen(BUN)(29.71±6.42)g·L-1(P<0.05);the mice of red ginseng group had a higher content of liver glycogen(10.46±3.21)g·kg-1(P<0.01)

and lower content of BUN(29.45±5.06)g·L-1(P<0.05);the mice of high pressure red ginseng group had a higher content of liver glycogen(9.87±2.44)g·kg-1(P<0.01). Conclusion: All the three types of ginseng showed anti-fatigue effects.
