Figure 4: Orthogonal partial least squares-discriminant analysis model results of bile metabolic profiling of normal control/acute blood stasis and acute blood stasis/Curcuma wenyujin rhizome in electrospray ionization + mode (a and c) and electrospray ionization - mode (b and d); orthogonal partial least squares-discriminant analysis s-plots of urine metabolic profiling of normal control/acute blood stasis and acute blood stasis/Curcuma wenyujin rhizome in electrospray ionization + mode (e and g) and electrospray ionization - mode (f and h). (One dot represent a bile or urine sample. Samples from different groups can be clearly distinguished, which indicates significant differences of different groups. The R2X (cum), R2Y (cum) and Q2 (cum) of principal component analysis model were all bigger than 0.70, indicating the model has good applicability)
