Vascular endothelial dysfunction is caused by dyslipidemia, hypertension, and deficiency of antioxidant systems. In this study, the protective effect of a flavonol, morin was investigated in high-fat diet (HFD)-induced dyslipidemia and vascular endothelium dysfunction. The dose-dependent attenuating effect of morin was tested at doses of 50 and 100 mg/kg/day in anmodel of HFD-induced dyslipidemia using rats whereas vascular endothelial reactivity was assessed in isolated rat aorta usingorgan bath setup. Morin administration in HFD-induced dyslipidemic rats for three weeks, resulted in a significant decrease in the body weight, LW/BW ratio as compared to rats treated with HFD only where the increase in body weight was observed. Significant reduction in the waist, BMI and lee index was also observed after morin treatment in HFD-induced dyslipidemic rats. In the lipid profile studies, HFD group showed a significant increase in the total cholesterol, triglyceride, LDL, and VLDL levels while HDL levels were decreased significantly, whereas morin treatment reversed all these parameters which were comparable to standard diet (SD) group. In theisolated aorta studies, HFD-induced endothelium dysfunction was observed, whereas it was reversed in the aorta of animals treated with morin at doses of 50 and 100 mg/kg/day, comparable to SD group. Morin treatment produced dose-dependent improvement in lipid profile and vascular endothelium protection, thus rationalizing its medicinal use in dyslipidemia and cardiovascular-related endothelial disorders.
