NMR-Based Metabonomic Studies on Stomach Heat and Cold Syndromes and Intervention Effects of the Corresponding Formulas
Figure 4
Heat map of the differential metabolites from rat serum in different groups. (a) SH and (b) SC. Each metabolite is represented by a single row of colored boxes, whereas columns correspond to different samples. Every concentration value was standardized according to the control group, that is, by subtracting mean and dividing by the standard deviation of healthy controls. In that way, the metabolites concentrations were expressed in values of standard deviation from the control group. Red and blue colors represent elevation or reduction of a given metabolite concentration, respectively.
