|Title:||Antihyperglycemic and antioxidant effect of hydroethanolic extract of Butea monosperma bark in diabetic mice|
|Abstract:||The antihyperglycemic, antihyperlipidemic and antioxidative properties of hydroethanolic extract of Butea monosperma bark were investigated in alloxan-induced diabetic mice. Alloxan administration resulted in higher blood glucose level and reduced hepatic glycogen content as compared to normal animals. Besides, serum lipid profile parameters such as total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) cholesterol were also found to be significantly elevated, whereas the level of high density lipoprotein (HDL) cholesterol was markedly reduced in diabetic animals. Oxidative damage in the tissues of diabetic mice was evidenced by a marked increase in the level of thiobarbituric acid reactive substances (TBARS), distinct decrease in reduced glutathione (GSH) content and declined activity of antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px). The daily treatment of diabetic animals with crude extract of B. monosperma bark (300 mg kg-1) for 45 days significantly lowered blood glucose level and elevated hepatic glycogen content, bringing the values close to those observed in normal control and glibenclamide-treated diabetic mice. Furthermore, the level of various lipid profile parameters was also reversed towards normal. TBARS and GSH also restored towards normal and the declined activity of antioxidant enzymes in diabetic animals was also normalized in crude extract administered mice, thus indicating the antioxidant efficacy of the drug in diabetes-induced oxidative damage. Significant antihyperglycemic and antioxidant potential of the crude extract of B. monosperma bark indicated that it may find use in the management of diabetes and resultant oxidative stress|
