Objective: The hypoglycemic, hepatorenalprotective, and antioxidant Activities of Cyperus rotundus rhizomes extract in an alloxan-induced diabetic rat model were investigated in this work. Methods: 25 Male rats were divided into 5 groups: normal control, diabetic control, diabetic of C. rotundus (200 mg/kg b.w), diabetic of C. rotundus (400 mg/kg b.w), diabetic of glibenclamide (0.6mg/kg).Treatments were administered orally for 6 weeks. Results: A single injection of alloxan to rats (150mg/kg b.w) caused pathological alterations in all studied parameters and histological structure of the pancreas. On the other hand, results showed that oral administration of C. rotundus rhizomes extract in dose of 200 and 400 mg/kg caused significant reduction in glucose, HbA1C%, α-amylase level and plasma lactate together with significant elevation in serum insulin, serum pyruvate with an improvement in insulin resistance. In line with amelioration of the diabetic state, C. rotundus rhizomes extract improved of the liver and kidney functions, and oxidative marker levels. Moreover, the extract succeeded to reduce the elevated serum total cholesterol, triglyceride (TG) and low-density lipoprotein- cholesterol (LDL-C) levels and to elevate the reduced high-density lipoprotein- cholesterol (HDL-C) level of diabetic rats. Conclusion: The investigation data concluded that C. rotundus rhizomes extract could be used as alternative treatments as antidiabetic, antioxidant and antihyperlipidemic, and agent as well as in liver and kidney protective in alloxan induced-diabetic rats. This may be related to the presence of saponin glycosides, polyphenols, flavonoids, and terpenoids in the ethanolic extract of C. rotundus rhizomes, which was discovered by phytochemical screening in this study to be present in the plant.
