Objective: To elucidate the in vivo hypoglycemic capability, antihyperglycemic and antihyperlipidemic activities of Pereskia bleo (Kunth) leaves extracts and bioactive fraction. Methods: The various solvent extracts of Pereskia bleo were investigated for the hypoglycemic and antihyperglycemic activities using a relevant in vivo normal rat model and streptozotocin-induced diabetic rat model with glibenclamide and metformin utilized as positive controls. The effects of the most potent extract and its bioactive fraction on the insulin level, lipid profile and body weight of the diabetic rats were also analyzed. Results: All the extracts showed no hypoglycemic effect while petroleum ether, chloroform and aqueous extracts demonstrated significant (P<0.05) reduction in blood sugar level in the intraperitoneal glucose tolerance test. Aqueous extract and aqueous fraction significantly (P<0.05) reduced the blood glucose level in streptozotocin-induced diabetic rats as early as day 6 compared to the diabetic control as well as significantly restored the serum insulin of diabetic rats. Moreover, the aqueous extract and aqueous fraction disclosed a significant (P<0.05) reduction in total cholesterol, triglycerides, and low-density lipoprotein levels. An elevation in high-density lipoprotein as well as improved body weight loss of the diabetic rats were also observed. Conclusions: In summary, Pereskia bleo appears effective in the management of diabetes and correlated impairments arising from high blood sugar level. Further studies will possibly bring about the discovery of effective and secure plant derived antidiabetic drugs.
