Abstract

Context: Tribulus terrestris (Zygophyllaceae) is a popular leafy prostrate branching herb used in folk medicine as a diuretic and urinary antiseptic. Aims: To evaluate the hepatoprotective and nephroprotective activities of the ethanolic plant extract and petroleum ether, dichloromethane and aqueous methanol fractions against CCl4 induced toxicity in adult Wistar rats. Methods: The total 95% ethanol extract at 200 and 400 mg/kg and petroleum ether, dichloromethane and aqueous methanol at 200 mg/kg was administered p.o. for seven days followed by one dose of CCl4 (1.25 mL/kg, p.o.) at day six. Serum and tissue parameters for both liver and kidney functions were measured. Histopathological study of both tissues was conducted. Results were compared with normal rats, negative controls receiving only CCl4 and positive controls treated with silymarin (10 mg/kg, p.o.). Results: Effect of the total 95% ethanol extract at 400 mg/kg on serum and tissue liver parameters were weak. However, protective effect on kidney was promising. The best effect was observed on the urea and creatinine levels. Both malondialdehyde and non-protein sulfhydryl groups in kidney tissues were improved to levels comparable with those obtained by silymarin. Conclusions: The current study confirmed the positive effect of the plant on the kidney tissues and function. The activity was trapped to the dichloromethane fraction that could provide pure active compounds.
