Differential metabolites and their classification. A The 1797 metabolites identified by collecting rat feces for metabolomic determination, which were classified and counted according to their chemical classification (Chemical Taxonomy) attribution information. B 17 differential metabolites in the EAN model group and NC group. C 34 differential metabolites in the LP treatment group and ENA model group. D 13 differential metabolites in the LB treatment group and ENA model group with strict OPLS-DA VIP > 1 and p < 0.05 as significant differential metabolites
