[Influence of salidroside from Rhodiola Sachalinensis A. Bor on some related indexes of free radical and energy metabolism after exercise in mice].

To study the anti-fatigue mechanism of salidroside from Rhodiola SachalinensisA.Bor (SRS)in anti-oxidation and energy metabolic systems in mice , some related indexes of free radical and energy metabolism after exercise were measured.Forty male mice were divided into four groups (n = 10): SRS sport group(SS), SRS quiet group(SQ),sport control group(SC), quiet control group (QC). The mice of SS and SQ groups received SRS solution of 150 ml/kg body weight per day for two weeks, while the mice of SC and QC groups received the same volume of distilled water. 30 min after the last treatment, the mice of SS and SC groups were forced to swim for 120 min without loads. then the biochemical parameters related to fatigue were determined.SRS could increase liver superoxide dismutase (SOD) , glutathione peroxidase (GSH-Px) activity of antioxidant enzymes and reduce the malondialdehyde (MDA) content, which might increase the body activity of antioxidant enzymes to play the role of anti-oxidation; SRS had some effect of stabilizing blood sugar, increasing liver glycogen and muscle glycogen reserves, preventing blood sugar, liver glycogen and muscle glycogen levels from reducing in long time exercise on mice; SRS could increase plasma total cholesterol (TC), triglyceride (TG) and free fatty acid (FFA) levels in exercise mice, and it had some effect on metabolism of fat under different conditions, and promoted the use of the role of fat.Influence of SRS on some related indexes of free radical and energy metabolism is one of the mechanisms of anti-exercise-induced fatigue of SRS.
