Abstract：Objective To optimize the purification methods of the polysaccharides from Hemicentrotus pulcherrimus gonad,and to evaluate their cytotoxic activity in vitro against human cancer cell lines.Methods The polysaccharides in H.pulcherrimus gonad were extracted with water,and the protein was removed by enzymic hydrolysis of papain and Sevage method,followed by dialyzed in flowing distilled water,precipitated in water and fully dried in progress.The total polysaccharide was separated by column chromatography on Sephacryl S-300 gel.The content of polysaccharides was measured with phenol-sulfuric acid method,and the antitumor effect was tested by MTT method.Results The optimum deproteinate effects were obtained by combination of enzymic hydrolysis of papain and Sevage method,and the optimized amount of papain was 100∶6 (the ration of the masses of defatted powder to papain),and the content of the purified total polysaccharide was 90%.The total polysaccharide and two separated polysaccharides showed anti-proliferative activity of Bel7402 cell lines.Conclusion The determined purification methods were applicable for the polysaccharides from H.pulcherrimus gonad for the simple and convenient operation,and that the purified polysaccharides displayed good physicochemical property and water-solubility.
