Duyun compound green tea (DCGT) is a healthy beverage with lipid-lowering effect commonly consumed by local people, but its mechanism is not very clear. We evaluated the effect of DCGT treatment on bile acids metabolism of mice with high-fat diet (HFD) - induced hyperlipidemia by biochemical indexes and metabolomics, and preliminarily determined the potential biomarkers and metabolic pathways of hyperlipidemia mice treated with DCGT as well as investigated its lipid-lowering mechanism. The results showed that DCGT treatment could reduce HFD - induced gain in weight and improve dyslipidemia. In addition, a total of 10 types of bile acids were detected, of which 7 changed bile acids metabolites were observed in HFD group mice. After DCGT treatment, glycocholic acid, tauroursodeoxycholic acid and taurochenodeoxycholic acid were significantly down-regulated, while hyodeoxycholic acid, deoxycholic acid and chenodeoxycholic acid were markedly up-regulated. These results demonstrated that DCGT treatment was able to make the bile acid metabolites in the liver of hyperlipidemia mice normal and alleviate hyperlipidemia by regulating the metabolites such as glycocholic acid, tauroursodeoxycholic acid and taurochenodeoxycholic, as well as the bile acid metabolic pathway and cholesterol metabolic pathway involved.
