Fig. 3. Pattern recognition analysis of 1D 1H NMR spectra recorded on aqueous extracts derived from five groups of C2C12 cells. (A) PCA scores plot of the five groups of cells. (B–E) PCA scores plots for NGG vs. Nor (B), Ala vs. NGG (C), Gln vs. NGG (D), Ala-Gln vs. NGG (E). (F) Hierarchical cluster analysis for the five groups of cells.
