Background: Diabetes mellitus (DM) is characterized by absolute or relative deficiencies in insulin secretion and/or insulin action associated with chronic hypoglycemia clinical research has confirmed the efficacy of several plant extracts in the amelioration of diabetic disorders. Aim of the work hypolipidemic and antioxidant activities of the aqueous extract of Cleome droseriloia was investigated in streptozotocin (STZ)-induced diabetic rats.Methods and Results: A single dose of STZ (60mg/Kg body weight) produced a decrease in hepatic glycogen and GSH contents, hepatic glucose-6-phosphate dehydrogenase, superoxide dismutase, activities and HDL- cholesterol, whereas, hepatic glucose-6-phosphatase activity and level of MDA, cholesterol, triglyceride, LDL-cholesterol and VLDL-cholesterol were increased. An aqueous extract of Cleome droseriloia (500, 750 and 1000mg/Kg or Gliclazide (100mg/Kg) was administered orally once daily for two weeks to STZ-induced diabetic rats ameliorated hyperglycemia, improved lipid profile, amelioration of antioxidants and restored the metabolic enzymes of glucose to the normal value in the liver of STZ-treated rats. In addition, the administration of Cleome droserifolia induced the secretion of insulin from pancreatic rats. Furthermore, the hypoglycemic efficacy of one dose of aqueous extract Cleome droserifolia has extended to 12 hours. The effects produced by Cleome droserifolia extract were found to be comparable with that of gliclazide.Conclusion: The present results suggested that Cleome droserifolia could be used as antidiabetic complement of diabetes mellitus. This may be related to its insulin-induction action. |
