ABSTRACT

BackgroundHemidesmus indicus is an important medicinal plant and extensively used in Ayurvedic and Unani system of medicine. The aim of the study was to evaluate the antioxidant, hypoglycaemic and hypolipidemic potential of methanolic extract of roots of Hemidesmus indicus (HIE) in streptozotocin (STZ) induced diabetic mice.MethodsHIE was analyzed by LC-MS to determine its phytochemical composition. The in-vitro antioxidant activity of HIE was analyzed through inhibition of free radical scavenging activity (FRSA), total antioxidant power (TAP) and reducing power. Diabetes in mice was induced by a single dose of STZ followed by HIE treatment. The antioxidative, hypoglycaemic and hypolipidemic activity were studied ex-vivo in tissues of diabetic mice.ResultsPhytochemical composition of hemidesmus indicus roots (HIE) revealed the presence of phenols, flavanoids, terpenoids and about 40 different phytoconstituents by LC-MS analysis. Inhibition of lipid peroxidation (LPO) and modulation in superoxide dismutase (SOD), catalase (CAT), glutathione-S- transferase (GST) activity and glutathione (GSH) content showed potent antioxidant activity of HIE in STZ induced diabetic mice, which was also substantiated by in-vitro antioxidant assays. The decrease in fasting blood glucose and serum lipid profile was also observed in mice administered HIE.ConclusionIt is proposed that HIE modulates the oxidant/antioxidant in favor of reducing oxidative stress, hypoglycemia and improved the lipid profile in treated groups.
