Abstract:
Objective To explore the effects of wogonin on hyperlipidemia in mice and clarify the molecule mechanism. Methods Thirty mice were evenly divided into three group normal control group,model control group and treatment group. The normal control group was given normal diet,the model control group received high-fat diet,the treatment group received high-fat diet with wogonin (500 mg·kg-1 ). Results The mice developed hyperlipidemia 12 weeks after starting the high-fat diet. The body weight,visceral fat and fat index were increased (P<0. 05). After treatment,these indices were reduced ( P < 0. 01). Wogonin significantly reduced the total cholesterol ( TC),low density lipoprotein ( LDL),high density lipoprotein (HDL),except the triglyceride (TG). Compared to the model control group,the hepatic lipase(HL) and lipoprotein lipase(LPL) activity in the treatment group were recovered (P<0. 05),but HMG-CoA reductase activity was inhibited ( P<0. 01). Mechanistic study suggested that the lipid-lowering effect might be related to the lipid synthesis genes (SREBP-1c,FAS, PPARγ) and the lipid metabolism genes (PPARα,CPT-1). Conclusion Wogonin can prevent hyperlipidemia,which might be related to the regulation of enzyme activity and the changes of lipid synthesis and oxidative metabolism.
