OBJECTIVE
To investigate the effects of extracts from Ajuga decumbens on anti-fatigue in mice.
METHODS
One hundred and twenty female Kunming (KM) mice were randomly divided into quiet control group, sport control group, positive control group and 3 experimental groups which were the low, medium and high dose group given the extracts from Ajuga decumbens. The low, medium and high dose group were given the extracts with 100 mg/kg, 200 mg/kg, 400 mg/kg by body weight of mice for 30 d, respectively, but the positive control group was given American ginseng granules, while the quiet control group and the sport control groups were treated with saline. After this, the exhausting time, the physio-biochemical indexes (including lactic acid, blood urea nitrogen, blood sugar, total cholesterol and triglyceride) in serum, the contents of muscle and liver glycogen, and the antioxidative indexes (including glutathione peroxidase, superoxide dismutase, catalase and malondialdehyde) of organs in mice were investigated.
RESULTS
The exhausting time, the number of red blood cell, the contents of hemoglobin and blood sugar, the contents of muscle and liver glycogen, and the activities of glutathione peroxidase, superoxide dismutase and catalase in organs of mice in the medium dose group and the high dose group were significantly more than those of the sport control group, but the contents of blood lactic acid, blood urea nitrogen and that of triglyceride and total cholesterol in serum, and the content of malondialdehyde in organs of mice in the medium dose group and the high dose group were significantly lower than those of the sport control group. And the effect of medium dose extracts from Ajuga decumbens on anti-fatigue was better than that of American ginseng granules.
CONCLUSIONS
The extracts from Ajuga decumbens has significant anti-fatigue effect in mice.
