Abstract: Protective effects of quercetin on myocardium ischemia repurfusion injury were studied in rats.Wistar rats were divided into 6 groups: pseudo operation; ischemia reperfusion operation; ischemia reperfusion with quercetin 0.2 mg/kg, 1.0 mg/kg and 5.0 mg/kg; ischemia reperfusion with verapamil 1 mg/kg.The results showed that quercetin possesses protective effects on myocardium ischemia reperfusion injury in rats and its mechanism may be related to inhibition of lipid peroxidation of quercetin.

Key words: quercetin, myocardial ischemia reperfusion, myocardial injury
