Figure 4: Establishment of the metabolic fingerprinting profiles of urine samples based on mass fragment profiles analysed by liquid chromatography/mass spectrometry system in negative ionization mode at 8th day. Principal components analysis (PCA) model results in negative mode (a). Loading plot of OPLS discriminant analysis in negative mode (b). Panel (c) illustrates the combination of S and VIP score plots constructed from the supervised OPLS analysis (ESI − mode). (d) PCA scores plot of silybin affecting on acute liver damage rat group (ESI − mode)
