LC–ESI–MS/MS differentially expressed metabolites (DEMs) detection. A The clustering plot showing a significant difference among the DCM and control group basing on the OPLS-DA model. B The volcano plot shows the difference in the expression level of metabolites between the DCM and control groups, and the statistical significance of the DEMs. C The VIP values of different metabolites. The red dots representing the up-regulated DEMs, and the green points representing the down-regulated DEMs. D After the qualitative and quantitative analysis of metabolites, log2 transformed, and the change of difference of DEMs is presented. Red is the up-regulated DEMs, and green is the down-regulated DEMs
