Emodin-8-O-β-D-glucopyranoside alleviates cholestasis by maintaining intestinal homeostasis and regulating lipids and bile acids metabolism in mice
Cholestatic liver disease(CLD) is caused by impaired bile flow due to obstruction of the biliary tract, and long-term exposure to bile acids in the liver triggers inflammation, eventually leading to liver toxicity and liver fibrosis. Emodin-8- O-β -D-glucopyranoside(EG) is anthraquinone compound that is widely found in traditional Chinese medicine. It possessed antioxidative and anti-inflammatory activities. However, the effect of EG on cholestatic liver injury(CLI) has not been explored. In this study, Alpha-naphthyl isothiocyanate(ANIT)-induced CLI mice were used to investigate the anti-cholestasis and hepatoprotective effects of EG through serum biochemical index detection, non-targeted metabolomics, lipidomics, and intestinal flora 16S rRNA sequencing. The results suggested that EG restores homeostasis of the gut microbiome while regulating bile acids metabolism and lipid-related metabolic pathways to reduce liver damage in ANIT-induced cholestasis. This study provides a new perspective on the mechanism of EG, and help offer a more natural approach to managing liver damage.
