Effect of silibinin on the hyperlipidemia in rats fed with high cholesterol diet

Abstract

Purpose: Despite current hypolipidemic drugs, the search for a more effective hypolipidemic agent is ongoing. In this study, it was aimed to investigate the effect of Silibinin on hyperlipidemia in rats fed high cholesterol diet (HCD). Materials and Methods: Rats were made obese. Rats were given egg yolk for 60 days and then 50 mg/kg, 100 mg/kg Silibinin were applied i.p. for 7 days. Results: The first and last weights of the rats were significantly different. While total cholesterol (TC), LDL, TG and VLDL levels increased significantly in the groups fed with HCD, HDL level reduced compared to control group (CG). OxLDL and TAS were significantly different between groups. Conclusion: The effects of Silibinin on serum LDL, TC, VLDL, HDL, TG, OxLDL levels and to observe the antioxidant effect, TAS and TOS were investigated in experimental obese rat models. It was concluded that Silibinin plays an effective role in lowering TG and LDL levels, increasing HDL levels and decreasing hepatic lipid accumulation in HCD rats at 100 mg/kg dose. The use of Silibinin does not cause antihyperlipidemic effect but has antioxidant effect.
