- 論文の詳細を見る
Coccolith is a calcified scale with species-specific fine structure produced by marine unicellular coccolithophorid algae, and consists of calcium carbonate crystals and organic matrices. EDTA-soluble organic materials extracted from coccoliths of Pleurochrysis carterae showed anti-calcification activity. They were separated by anion-exchange HPLC, and two fractions, fractions A and B, were obtained. Fraction B, which was more active than fraction A, was further separated into six consecutive fractions, B1-B6, by second anion-exchange HPLC. ^1H NMR spectral analyses of these fractions suggested that a novel acidic polysaccharide, designated CMAP, existed throughout B1-B6 and that the latter four fractions mainly contained another acidic polysaccharide, PS-2, characterized previously. Since PS-2 did not show anti-calcification activity, CMAP was found to be the active principle.
