Metabolomic alterations of BGZ treatment on Yinsyn and Yangsyn rats (N = 8). A–B Scatter plot of liver metabolites in all groups determined by PCA in ESI- mode (A) and ESI + mode (B). C–D Scatter plot of liver metabolites between the Yangsyn+BGZ and Yangsyn groups determined by OPLS-DA in ESI- mode (C) and ESI + mode (D). E–F Scatter plot of liver metabolites between the Yinsyn+BGZ and Yinsyn groups determined by OPLS-DA in ESI- mode (E) and ESI + mode (F). G Heatmap of the metabolites identified. Color depth represents the variation trend of the relative abundance of metabolites, the red color represents up-regulated metabolites, and the blue color represents down-regulated metabolites
