Purification and structural characterization of Chinese yam polysaccharide were investigated and its activities were analyzed. Results indicated that a single component polysaccharide with a molecular weight of 16,619 Da was obtained after hot water extraction with sequential sevage deproteinization, HSCCC and Sephadex G-100 size-exclusion chromatography. The FTIR analysis showed that it had characteristic absorptive peaks and contained uronic acid. The methylation and GC-MS analysis showed… CONTINUE READING
