| Abstract: | Acidic polysccharide was extracted by boiling water from Microcystic aeruginosa, isolated and purified by DEAE-52 gel column. IR, UV, HPLC and 13C-NMR were used for the structural analysis. Results showed that MAAP was a new acidic polysaccharide, it's molecular weigh was 2.0028 x 10(5), and it's chain was composed of a-glycoside linkage. The component of MAAP was identified as rhamnose, xylose, arabinose, galactose and galacturonic acid. |
