Sodium alginate and fucoidin were further purified, the purity of which was demonstrated homogeneously by chromatography on a sephadex G-75 column and acetate cellulose membrane electrophoresis.
METHODS The columnchromatography of silica gel and sephadex were used to isolate those constituents. IR, 1H-NMR and MS were used to identify the compounds.
