Isolation, Structural Characterization and Cell Proliferation Activity of Abalone Polysaccharide from Different Regions

The polysaccharides were isolated from the abalone Haliotis discus hannai Ino cultivated from Qingdao and Fujian, and their proliferation activity on HepG2 cell was assessed. The monosaccharide composition of the abalone polysaccharides from Qingdao and Fujian was different, which might be related to their different geographical location and breeding conditions. The proliferation activity of abalone polysaccharide from Qingdao was better than that from Fujian. AAP, AVAP I and AVAP II were further isolated from the abalone polysaccharide from Qingdao, the cell proliferation activity of AVAP I and AVAP II was better than AAP, which might be depended on their monosaccharide composition. Our study would provide preliminary data for the high value utilization of abalone polysaccharides.
