Metabolite Markers for Characterizing Sasang Constitution Type through GC-MS and ¹H NMR-Based Metabolomics Study

Figure 1

OPLS-DA score (a, c, and e) and OPLS-DA loading (b, d, and f) plots derived from ¹H NMR spectra of serum samples for pairwise comparison of metabolic difference between Tae-Eum and So-Yang (a and b), Tae-Eum and So-Eum (c and d), and So-Yang and So-Eum (e and f), demonstrating metabolic differences in serum between SC types. Reliabilities and predictabilities of OPLS-DA models were indicated by R²X and (g), respectively. HDL, high-density lipoprotein; LDL, low-density lipoprotein; FAs, fatty acids. Panels (h) show scatter dot plots of identified metabolites.
