Citri Grandis Exocarpium (CGE), is renowned for its dual use in medicine and food, being well-known beneficial antioxidant anti-inflammatory effects. However, the changes of chemical composition activity CGE during storage (aging) process are still unclear. In this study, We examined metabolites samples aged 1 year (CG1), 3 years (CG3) 5 (CG5), mainly through comprehensive metabolomics techniques. The results indicated that analysis extracts by ultra-high-performance liquid chromatography-quadrupole/time flight mass spectrometry (UHPLC-QTOF-MS/MS) resulted detection 1249 metabolites. A total 57 differential were identified as potential markers distinguishing CGEs different aging chemometrics methods, including naringin, among others. KEGG annotation, enrichment topology revealed biosynthesis flavonoids was a key metabolic pathway CEG, involving 14 determined Total flavonoids, naringenin, butin, 7',4-dihydroxyflavone, phlorizin have been associated with activity. These clarified effects time on accumulation CGE, provided scientific basis understanding mechanism process.
