Figure 2. Boxplot of 13 components in different batches of samples. The circle and asterisk were the symbols used for outliers and the number indicates the batch number. Two components (W1 and W2) were unknown. Sample 1–4 stand for Strongylocentrotus nudus. Sample 5, and 7–12 stand for Glyptocidaris crenularis. Sample 6, 13 and 14 stand for Anthocidaris crassispina.

Figure 3. Score (A) and loading (B) plot of PCA. The numbers 1–14 shown in (A) refer to the sample number. The numbers 1–103 shown in (B) indicate the chromatographic peaks in HPLC fingerprints. Sample 1–4 stand for Strongylocentrotus nudus. Sample 5 and 7–12 stand for Glyptocidaris crenularis. Sample 6, 13 and 14 stand for Anthocidaris crassispina.

Figure 4. Hierarchical cluster analysis based on between-groups the average-linkage method. Dendrograms in (A–C) were based on the areas of common peaks in fingerprints with three similarity algorithms: Euclidean distance (A); cosine of angle (B) and Pearson correlation (C). Sample 1–4 stand for Strongylocentrotus nudus. Sample 5 and 7–12 stand for Glyptocidaris crenularis. Sample 6, 13 and 14 stand for Anthocidaris crassispina.
