OBJECTIVE To detect the content of polysaccharide frome Sargassum fusiforme, to analyze the monosaccharide composition of the polysaccharides and to provide some reference for research on chemistry and pharmacology. METHODS UV-spectrophotometer and phenol-sulfuric method were used, the detection wavelength was 490nm. The monosaccharide composition was determined by HPCE. RESULTS The percent of polysaccharide in Sargassum fusiforme was 53.46% and average recovery was 99.37%, RSD=2.19%. Polysaccharides from S...
