Objective: To evaluate the antidiabetic effects of Emilia coccinea (Ec) (Asteraceae), Scoparia dulcis (Sd) (Plantaginaceae) and Tetracarpidium conophorum (Tc) (Euphorbiaceae) aqueous extracts mixture (EcSdTc) in rats. Methodology: Single plant aqueous extracts (Ec, Sd and Tc) and their mixtures (EcSd, EcTc, SdTc and EcSdTc) (each at the doses of 125 and 250 mg/kg body weight respectively) were evaluated in acute administration on blood glucose in normal, glucose-overloaded and diabetic rats;then EcSdTc mixture was assessed in prolonged administration (21 days) on blood glucose, body weight, serum biochemical and antioxidant parameters in diabetic rats. Diabetes was induced by single intraperitoneal administration of streptozotocin (STZ;50 mg/kg), and glibenclamide (10 mg/kg) was used as standard drug. Results: In acute administration, EcTc250, EcSdTc125, SdTc250, SdTc125, EcSd250, and EcSdTc250 extracts mixtures reduced (p Conclusion: EcSdTc aqueous extracts mixture has potent hypoglycemic and antidiabetic effects, probably due to their bioactive compounds synergistic and/or additive actions, justifying its traditional use as alternative remedies.展开更多
