Oranges and mandarins in Chongqing, China, are mostly processed for juice their peels wasted or landfilled. To add value, it is essential to utilize the extract useful materials, such as citrus oils (CEOs). Here, we report metabolome analysis of Citrus x sinensis (CS) reticulata (CR). In total, 793 metabolites were detected CS CR peels, which 242 differentially accumulated. The grouped into 12 compound classes. Terpenoids highest accumulated class compounds followed by phenols alcohols both fruit peels. rich all types compounds, whereas showed a relatively lower content compounds. ?-phellandrene, beta-ocimene, 1,3,6-octatriene,3,7-dimethyl, d-limonene. Overall, higher diversity than CS. peel extracts antibacterial effects against Escherichia coli, Staphylococcus aureus, Bacillus subtilis. from similar E. coli B. subtilis, while more effective S. aureus. our study concludes that should not be owing CEOs respective activities.
