ABSTRACT
Objective To study the influence of dihydromyricetin on the oxidation and non-enzymatic glycosylation in impaired glucose tolerance rats.Methods Animal model of impaired glucose tolerance rat was built by intragastrical(i.g.) injection of D-galactose generally.After 8 weeks intragastrical(i.g.) injection of dihydromyricetin(experimental group) and metformin (positive control),the levels of fasting blood glucose and tow-hour postprandial blood glucose,the insulin level and its resistance index,the levels of glycosylated hemoglobin (GHb) and advanced glycation end-products(AGEs) were detected,and the activities of superoxide dismutase(SOD) and glutathione peroxidase (GSH-Px),the content of malondiadehyde(MDA) were determined respectively.Results Compared with model group,dihydromyricetin decreased the level of two-hour postprandial blood glucose (P0.05).Conclusion Dihydromyricetin can significantly improve the state of impaired glucose tolerance rats; the mechanism may be related to its effect of improving the antioxidant activity of GSH-Px,inhibiting non-enzymatic glycation,lowering body oxidative stress and insulin resistance and promoting the use of blood glucose in peripheral organizations.
