Figure 2.

The image includes six panels: (A) a Venn diagram showing the overlap of five groups, labeled CZS-FC, BM-TC, AH-AC, SK-FC, and YM-AC; (B) a pie chart depicting the distribution of various compound classes, such as lipids, organic acids, and alkaloids; (C) and (D) scatter plots showing PCA analysis with groups color-coded and labeled; (E) a dot plot with pathways and corresponding p-values, dot size representing count; (F) bar graphs comparing levels of several compounds across different groups, with significance indicated by asterisks.

Untargeted metabolomic analysis of FCB. (A) Comparative metabolite profiles of FCB from different sources; (B) Metabolite category distribution; (C) PLS-DA score plot in positive ion mode; (D) PLS-DA score plot in negative ion mode; (E) KEGG pathway enrichment analysis; (F) Content of five key metabolites in FCB from different sources. Asterisks are used to denote statistically significant differences: The significance of the results is indicated by the following p-values: p<0.05, ** p<0.01, p<0.001, and **** p<0.0001, among others.
