Abstract:
Objective Study the effect of chlorogenie acids(CHA)on insulin resistance in obese rats induced by high‐fat diet . Methods We induced the obese rat model by feeding high‐fat diet ,obese rat model were divided into 4 groups:model group ,piogli‐tazone group(4 .5 mg/kg) ,CHA large dose group and group ,and finally determinated the levels of glucose tolerance ,serum insulin , serum lipid profiles and others .Results CHA showed a higher anti‐obesity activity with lower rate of increase of obese rats′body weights ,reversingglucose intolerance induced by high‐fat diet ,ameliorating the hyperinsulinemia ,decreaseing the levels of TG and TC ,and increase liver glycogen and muscle glycogen level compared with other group which treated with high‐fat diet .And in‐creased HOMA‐ISI ,decreased HOMA‐IR .Conclusion CHA can ameliorate the symptoms of insulin resistance in obese rats ,which mechanism may be related with CHA can stimulate glucose uptake and utilization by peripheral tissues ,and decrease the the serum levels of FFA ,decrease oxygen stress ,prevent and cure the injury induced by lipid peroxidation .
