Figure 1

Chemometric analysis by a 3D score plot of the PCA. A score plot from pattern recognition (PCA) of the spectra is shown. The data sets are Pareto scaled. Overall, the plot can successfully distinguish the four groups of ginseng (N = 5). (PC1: R2 = 0.48, Q2 = 0.42; PC2: R2 = 0.71, Q2 = 0.59; PC4: R2 = 0.86, Q2 = 0.73).
