Supplementary Material

Under the optimized experimental conditions, SDAPCI-MS fingerprints of 24 propolis samples were obtained for ranges of m/z 70-500 and m/z 200-350. According to the classification of PCA (Figure 2), representative fingerprints of four Chinese propolis samples, GZ-1, GS, AH and FJ-2, were exhibited in Supplemental Figure 1 (m/z 70-500) and Supplemental Figure 2 (m/z 200-350).
