Oxidative stress plays a vital role in diabetic complications. To suppress the oxidative stress mediated damage in diabetic pathophysiology, a special focus has been given on composite extract (CE) and making small dose of naturally occurring antidiabetic plants leaf and fruits. The aim of the present study was to evaluate the beneficial role of CE against alloxan- (ALX-) induced diabetes of Wistar strain rats. A dose-dependent study for CE (25, 50, and 100？mg/kg body weight) was carried out to find the effective dose of the composite compound in ALX-induced diabetic rats. ALX exposure elevated the blood glucose, plasma advanced oxidation product (AOPP), sialic acid demonstrating disturbed antioxidant status.CE at a dose of 100？mg/kg body weight restored/minimised these alterations towards normal values. In conclusion, small dose of CE possesses the capability of ameliorating the oxidative stress in ALX-induced diabetes and thus could be a promising approach in lessening diabetic complications. 1. Introduction Diabetes mellitus is a syndrome characterized by chronic hyperglycemia and associated with absolute or relative deficiency in insulin secretion or insulin action . Herbal medicine has been used as an antidiabetic therapy alone, along with insulin or other synthetic oral hypoglycemic agents. The use of synthetic agents is frequently associated with several undesirable side effects and fails to correct the fundamental biochemical lesion and diabetic complications . The search for a cure for diabetes mellitus continues along with traditional and alternative medicine. Many herbal supplements have been used for the treatment of diabetes, but the scientific evidence to support their effectiveness has only been investigated for a few . To suppress the oxidative stress mediated damage in diabetic pathophysiology, researchers usually look for naturally occurring antioxidants [4, 5]. Diabetes mellitus (DM) is strongly associated with oxidative stress . Chronic hyperglycemia resulting from diabetes brings about a rise in oxidative stress due to overproduction of reactive oxygen species (ROS) as a result of glucose-autoxidation and protein glycosylation. Generation of ROS leads to oxidative damage of the structural components (such as lipids, DNA and proteins) of cells which culminate into complications affecting the eyes, kidney, nerves, and blood vessels . Oxidative insult in cells is also created by the impairment in functioning of endogenous antioxidant enzymes because of nonenzymatic glycosylation and oxidation . Aegle marmelos is a
