Abstract
BackgroundAegle marmelos (L.) Corr. (Rutaceae), commonly known as bael, is used to treat fevers, abdomen pain, palpitation of the heart, urinary troubles, melancholia, anorexia, dyspepsia, diabetes and diarrhea in Indian traditional systems of medicine. The object of the present study was to evaluate the antidiabetic, antihyperlipidemic and antioxidant oxidative stress of umbelliferone β-D-galactopyranoside (UFG) from stem bark of Aegle marmelos Correa. in STZ (streptozotocin) induced diabetic rat.MethodsDiabetes was induced in rat by single intraperitoneal injection of STZ (60 mg/kg). The rat was divided into the following groups; I – normal control, II – diabetic control, III – UFG (10 mg/kg), IV – UFG (20 mg/kg), V – UFG (40 mg/kg), VI – Glibenclamide (10 mg/kg, p.o., once a daily dose). Diabetes was measured by change the level blood glucose, plasma insulin and the oxidative stress were assessed in the liver by estimation of the level of antioxidant markers i.e. superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and Malondialdehyde (MDA) and antihyperlipidemic effect was measured by estimation of total cholesterol, triglycerides, LDL (low density lipoprotein) cholesterol, HDL (high density lipoprotein) cholesterol, VLDL (very low density lipoprotein) cholesterol. However in a study, the increased body weight was observed and utilization of glucose was in the oral glucose tolerance test.ResultDaily oral administration of different dose of UFG for 28 days showed significantly (P < 0.001) decreased in fasting blood glucose level and improve plasma insulin level as compared to the diabetic control group. Also it significantly (P < 0.001) decreased the level of glycated hemoglobin, glucose-6-phosphatase, fructose-1-6-biphosphate and increased the level of hexokinase. UFG treatment decreased liver MDA and increased the level of SOD, GPx and CAT. UFG treatment of lipids it’s increased the level of cholesterol, triglycerides, VLDL, LDL cholesterol and decreased the level of HDL cholesterol. Histologically, inflammatory cell in blood vessels, intercalated disc, fat degeneration and focal necrosis observed in diabetic rat organ but was less obvious in UFG treated groups. The mechanism of action of UFG may be due to the increased level of pancreatic insulin secretion and effect on the antioxidant marker.ConclusionUFG posses an antidiabetic, antioxidant and antihyperlipidemic effect on the STZ induced diabetic rat. Hence it could be the better choice to cure the diabetes.

According to the reports that, 135 million adults affected from the diabetes mellitus in year 1995 worldwide and the data will increase to 300 million in the year 2025 [1,2]
Major reason is generation of free radical formation, free radical generation caused by degeneration of carbohydrates, lipid and protein metabolism by increased blood glucose level resulting from the defects in insulin secretion, insulin action or both
Summary
Aegle marmelos (L.) Corr. (Rutaceae), commonly known as bael, is used to treat fevers, abdomen pain, palpitation of the heart, urinary troubles, melancholia, anorexia, dyspepsia, diabetes and diarrhea in Indian traditional systems of medicine. The object of the present study was to evaluate the antidiabetic, antihyperlipidemic and antioxidant oxidative stress of umbelliferone β-D-galactopyranoside (UFG) from stem bark of Aegle marmelos Correa. Elevated glucose production causes oxidative stress and as a result there is increase in mitochondrial reactive oxygen species (ROS), non-enzymatic glycation of proteins and glucose autoxidation [3]. In diabetes, increased oxidative stress is due to generation of free radical and reduction of antioxidant defenses [4]. A lot of classes of synthetic drug are available in the market but quite a few herbal drugs are being employed in the treatment of diabetes mellitus. Still researching is going on to find out the more effective herbal drug to cure the diabetes and reduced the free radical formation with minimized side effect
