A metabolomics study on the mechanisms of Gardeniae fructus against α‐naphthylisothiocyanate‐induced cholestatic liver injury

Abstract

AbstractGardeniae fructus (GF) is known for its various beneficial effects on cholestatic liver injury (CLI). However, the biological mechanisms through which GF regulates CLI have not been fully elucidated. This study aimed to explore the potential mechanisms of GF against α‐naphthylisothiocyanate (ANIT)‐induced CLI. First, HPLC technology was used to analyze the chemical profile of the GF extract. Second, the effects of GF on serum biochemical indicators and liver histopathology were examined. Lastly, metabolomics was utilized to study the changes in liver metabolites and clarify the associated metabolic pathways. In chemical analysis, 10 components were identified in the GF extract. GF treatment regulated serum biochemical indicators in ANIT‐induced CLI model rats and alleviated liver histological damage. Metabolomics identified 26 endogenous metabolites as biomarkers of ANIT‐induced CLI, with 23 biomarkers returning to normal levels, particularly involving primary bile acid biosynthesis, glycerophospholipid metabolism, tryptophan metabolism, and arachidonic acid metabolism. GF shows promise in alleviating ANIT‐induced CLI by modulating multiple pathways.
