Study on the Effect of the Polysaccharide from Pu-erh Tea on the Anti-fatigue

[Objective] The role of the polysaccharide of Pu-erh tea in the anti-fatigue was studied.[Method] 30 health mice were divided into randomly into 3 groups(half male and half female in each group) and the GroupⅠ was not treated as the CK,GroupⅡ was fed with the water solution with the polysaccharide from Pu-erh tea and Group Ⅲ was fed with Pu-erh tea water.The moving endurance time and the quantity of blood urea nitrogen of the mice were tested after the continuous 14 days′feeding.[Results] The moving endurance time of GroupⅠ,GroupⅡ and GroupⅢ was(187.2±4.7) minutes,(438.5±20.3) minutes and(270.3±7.8) minutes and the value of blood urea nitrogen of GroupⅠ,GroupⅡ and GroupⅢ was(8.168 7±0.194 4) mmol/L,(1.680 6±0.156 8) mmol/L and(4.231 0±0.349 2) mmol/L.It can be seen that the formation of the blood urea nitrogen in mouse fed with the solution of the polysaccharide or the extract of Pu-erh tea could be significantly reduced,and meanwhile,the moving endurance of mouse could be strengthened for much longer swimming time.The effect of tea polysaccharide on mouse was better than that of the tea extract.[Conclusion] The tea polysaccharide had a certain effect on anti-fatigue of mouse.
