Apple polyphenols (APP) can reduce obesity. However, the effects of APP on abdominal subcutaneous adipose tissue (aSAT) at metabolic level were unclear. In this study, 5-week APP intervenes were conducted on 10-week high-fat diet (HFD) feeding mice with doses of 200 and 500 mg/kg b.w./day, followed by ultra-high-performance liquid chromatography-mass spectrometry based untargeted metabolomics analysis. As expected, APP obviously reversed aSAT weight and index, as well as activities of myeloperoxidase, glutathione peroxidase, superoxide dismutase and catalase. Euclidean distance between HFD and normal chow diet (NCD) group was shortened. 64 and 127 differential metabolites were found in 200 and 500 mg/kg b.w./day group, with 12 and 13 changed pathways, respectively. Specifically, APP restored glycolysis, tricarboxylic acid cycle, amino acid metabolism, and lipid metabolism as dose-dependent manner. Finally, glucose-6-phosphate, xanthine and tyrosine were selected as critical junctures. Collectively, these findings underscore the potential of APP in reversing molecular alterations in aSAT.
