Quercetin is a herbal antioxidant commonly found in nature. It is frequently used as supplement because of its beneficial effects on health. Objective: The aim of this study was to analyze effects of chronic administration of quercetin on triglyceride and blood glucose levels on diet-induced obesity in rats. Methode: Male Wistar rats aged 8-weeks weighing ± 150 g were distributed randomly into five groups (n=4). As normal control, one group received standard diet. Four other groups were induced

Then, three of four obese groups received standard diet and each group were treated with quercetin with doses of 2, 10, and 50 mg/kg body weight for 10 weeks, whereas one other group received standard diet only (obese control group). Finally, triglyceride and blood glucose levels were measured. Result: Significant blood glucose reduction was found in all three quarcetine-treated groups as compared to obese control group (p<0.05), but greatest reduction was found on the group treated with 50 mg/kg quercetine. However, although all quercetin-treated groups showed lower levels of triglyceride as compared to obese control groups, significant reduction was only achieved by group treated with 50 mg/kg quarcetin (p<0.05). Conclusion: Quercetin had beneficial effect for reducing blood glucose and triglyceride levels on diet-induced obesity in rats.
