Aim of the study: Aim of the present study was to evaluate the anti-obesity activity of chloroform:methanol extract of P. integrifolia (CMPI) in mice fed with cafeteria diet. Materials and Methods: Female Swiss Albino mice were divided into six groups, which received normal and cafeteria diet, standard drug simvastatin (10 mg/kg) and CMPI (50, 100 and 200 mg/kg) daily for 40 days. Parameters such as body weight, body mass index (BMI), Lee index of obesity (LIO), food consumption, locomotor behavior, serum glucose, triglyceride, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), atherogenic index, organ weight and organ fat pad weight were studied for evaluating the anti-obesity activity of P. integrifolia. High performance liquid chromatography (HPLC) fingerprint profile of chloroform-methanol extract was also studied using quercetin as the reference standard. Results: There was a significant increase in body weight, BMI, LIO, food consumption, organ weight (liver and small intestine), organ fat pad weight (mesenteric and peri-renal fat pad) and in the levels of serum glucose, triglyceride, total cholesterol, LDL and VLDL with a significant decrease in locomotor behavior (ambulation, rearing, grooming) and HDL level in cafeteria diet group. Animals treated with CMPI showed dose dependent activity. P. integrifolia (200 mg/kg) supplementation attenuated all the above alterations, which indicates the anti-obesity activity. HPLC fingerprint profile of CMPI showed two peaks in the solvent system of 50 mm potassium diphosphate (pH-3 with ortho phosphoric acid): Methanol (30:70 v/v) at 360 nm. Conclusion: Present findings suggest that, CMPI possessed anti-obesity activity that substantiated its ethno-medicinal use in the treatment of obesity.
