Its main manifestation includes abnormal metabolism of carbohydrates and lipids and inappropriate hyperglycemia that is caused by absolute or relative insulin deficiency. It affects humankind worldwide. OBJECTIVES: Our research was aimed to observe antihyperglycemic activity of thymoquinone and oleuropein. MATERIALS AND METHODS: In this study, rats were divided into six groups, 6 rats in each. Diabetes was inducted by streptozotocin (STZ). The level of fasting blood glucose was determined for each rats during the experiment, doses of thymoquinone and oleuropein (3 mg/kg and 5 mg/kg) for both, were injected intraperitoneal. Pancreatic tissues were investigated to compare β-cells in diabetic and treated rats. RESULT AND CONCLUSION: It was found that thymoquinone and oleuropein significantly decrease serum Glucose levels in STZ induced diabetic rats.
