As a source of potent anti-inflammatory traditional medicines, the quantitative chromatographic fingerprints of sea urchin shell polysaccharides were well established via pre-column derivatization high performance liquid chromatography (HPLC) analysis. Based on the quantitative results, the content of fucose and glucose could be used as preliminary distinguishing indicators among three sea urchin shell species. Besides, the anti-inflammatory activities of the polysaccharides from sea urchin shells and their gonads were also determined. The gonad polysaccharide of Anthocidaris crassispina showed the most potent anti-inflammatory activity among all samples tested.

	Figure 1. HPLC chromatogram of sea urchin shell polysaccharide hydrolysate. 11 monosaccharide compositions were determined. W1 and W2 were unknown. 13-Methyl-1-phenyl-2-pyrazolin-5-one (PMP), 2 Mannose (Man), 3 Glucosamine (GlcN), 4 Ribose (Rib), 5 Rhamnose (Rham), 6 Glucuronic acid (GlcUA), 7 Galactosamine (GalN), 8 Glucose (Glc), 9 Galactose (Gal), 10 Xylose (Xyl), 11 Arabinose (Ara), 12 Fucose (Fuc).
	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 1â€“4 stand for Strongylocentrotus nudus. Sample 5, and 7â€“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 1â€“14 shown in (A) refer to the sample number. The numbers 1â€“103 shown in (B) indicate the chromatographic peaks in HPLC fingerprints. Sample 1â€“4 stand for Strongylocentrotus nudus. Sample 5 and 7â€“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 (Aâ€“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 1â€“4 stand for Strongylocentrotus nudus. Sample 5 and 7â€“12 stand for Glyptocidaris crenularis. Sample 6, 13 and 14 stand for Anthocidaris crassispina.
