Anti-diabetic, anti-oxidant and anti-adipogenic potential of quercetin rich ethyl acetate fraction of prunus persica

Abstract

Background: Diabetes mellitus is enfeebling threatening diseases with continuously increasing rates of incidence and mortality and it may rise tremendously by 2025. Objective: Quercetin rich ethyl acetate fraction (PP-EtOA) of leaves of Prunus persica was evaluated for antidiabetic, anti-oxidant and anti-adipogenic activities. Material and Methods: Streptozotocin (STZ)-induced diabetic rat model, oral glucose tolerance test (OGTT) and normalglycemic rat models were investigated at the doseof 100 and 200 mg/kg,p.o. of PP-EtOA. Results: At 200 mg/kg, significant anti-hyperglycaemic activity(p<0.05) was observed in all the rat models. In STZ induced diabetic rat model, improvement in body weight and lipid profile was also observed.DPPH (2,2’-diphenyl-1-picrylhydrazyl) free radical scavenging method showed dose dependent scavenging. Preadipocyte differentiation assay (3T3-L1) showed significant inhibition of differentiation. HPLC fingerprinting analysis of fraction was also performed. Conclusion: PP-EtOA possesses potent free radical scavenging property. Its antihyperglycemic and anti-adipogenic activities may be due to quercetin (flavonoid) and may prove to be effective in the treatment of diabetes mellitus and diabetes driven dyslipidemic conditions.
