Compatibility of Polygonati Rhizoma and Angelicae Sinensis Radix enhance the alleviation of metabolic dysfunction-associated fatty liver disease by promoting fatty acid β-oxidation

Abstract

Jiuzhuan Huangjing Pills (JHP) composed of Polygonati Rhizoma (PR) and Angelicae Sinensis Radix (ASR) remedied mitochondria to cure metabolic dysfunction-associated fatty liver disease (MAFLD). However, a comparison of the anti-MAFLD ability between JHP prescription and PR and ASR single-medicines in MAFLD has not been performed, and the action mechanisms and substances remain unknown. Our results show that JHP, PR and ASR decreased serum and liver lipid levels. The effects of JHP were stronger than those of PR and ASR. JHP, PR and ASR afforded protection to mitochondrial ultrastructure, and regulated oxidative stress and energy metabolism in mitochondria. JHP also regulated the expression of β-oxidation genes, which were not regulated by PR and ASR. JHP-, PR- and ASR-derived components in mitochondrial extracts regulated oxidative stress, energy metabolism, and β-oxidation gene expression and alleviated cellular steatosis. Four, six and eleven compounds were identified in mitochondrial extracts from PR-, ASR- and JHP-treated rats, respectively. The data suggest that JHP, PR and ASR alleviated MAFLD by remedying mitochondria, while the ability of JHP was stronger than that of PR and ASR, which was involved with the β-oxidation promotion. The compounds identified may be the main ingredients in the three extracts active in MAFLD improvement.
