Abstract Title: 

Cocoa powder extracts exhibits hypolipidemic potential in cholesterol-fed rats.


INTRODUCTION: Hypercholesterolemia and oxidative stress are risk factors of cardiovascular diseases.OBJECTIVES: This study investigated the hypolipidemic effect of cocoa powder extract (CPE) in an experimental model of hypercholesterolemia, using Questran as a reference.METHODS: Hypercholesterolemia in rats was induced by oral administration of 30 mg/kg cholesterol for eight weeks. Three groups concurrently received Questran (0.26 g/kgb) and CPE (100 mg/kg and 200 mg/kg) respectively. Hypercholesterolemia and dyslipidemia were assessed by lipid profile. Reduced glutathione (GSH), Superoxide dismutase (SOD), Catalase (CAT), Glutathione-S-transferase (GST) and malondialdehyde (MDA) level were also assessed to evaluate the antioxidant status of rats.RESULTS: There was 56% and 97% increase in total and LDL-cholesterol and 59% decrease in HDL-cholesterol levels on cholesterol administration. Concurrent administration of CPE (100 mg/kg) significantly (p
