Hepatoprotective Effects of Tribulus terrestris Hydro-Alcholic Extract on Non-Alcoholic Fatty Liver- Induced Rats

Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris (T. terrestris) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n=6). Animals in experimental groups were received high fructose diet (70 %) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey's post-hoc multiple comparison test and P<0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P<0.05) and serum lipid profiles (P<0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P<0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.
