Abstract:
A polysaccharide SPPC 1 was isolated from spirulina platensis by acetone fractional precipation, free protein was removed by trichloroacetic acid(TCA). Purification of the polysaccharide by Sephadex G 75 colume and CM Sephadex C 50 colume.The homogeneity of this polysaccharide was proved by HPLC and CE. molecular weight was 1.62?10 6. GC showed that the glycoconjugate was composed of Rha,Xyl,Man and Glc. Molar ratio is Rha:Xyl:Man:Glc=6.24:0.37:0.13:0.71. IR, 1HNMR spectrum indicated the presence of ? linkage glycoside. ESR experiment showed that SPPC 1 could eliminate O . 2 radicals.
