Fast Differential Analysis of Propolis Using Surface Desorption Atmospheric Pressure Chemical Ionization Mass Spectrometry

Figure 2

PCA analysis of SDAPCI-MS fingerprints. PCA loading plots (ions) for 70–500 m/z (a) and 200–350 m/z (d). PCA score plots for SDAPCI-MS fingerprints of propolis and their colors for 70–500 m/z (b) and 200–350 m/z (e). PCA score plots and their climatic zones for 70–500 m/z (c) and 200–350 m/z (f). For (a) and (d), the numbers of spots mean the m/z of the ions. For (b), (c), (e), and (f), the numbers are their sample number. See Table 1 for characteristics of the samples.
