Research on the Mechanism of Tea Polysaccharide Reducing Blood Glucose in Vitro

Abstract:

The target of this manuscript is to elucidate the mechanism of TPS reducing blood glucose,for this,the scavenging effect of 89% and 51% tea polysaccharides (TPS) on hydroxyl radical,superoxide radical key carbohydrate metabolic enzymes activities,and the glucose transportation to 3T3-L1 were careful investigated in vitro Results showed that the abilities of scanvenging hydroxyl radical and superoxide radical of TPS with lower purity was abvious,while,that with higher purity was not obvious.The effect on α-glucosidase activities and transportation of glucose to 3T3-L1 cell were also no obvious.However,TPS significantly enhanced the activities of hexokinase(HK) and glucokinase (GK).
