英文摘要: Desulfation of a fucoidan from Saccharina japonica by treatment with DMSO-MeOH resulted in partial degradation of polymeric molecules by methanolysis giving rise to a mixture of neutral, monosulfated, and disulfated fucooligosaccharides in the form of methyl glycosides. These oligomeric fragments were characterized by ESI-MS and ESI-CID-MS/MS. It was found that oligosaccharide structures coincided with the polysaccharide backbone built up mainly of (1 -> 3)-linked fucose residues sulfated at positions 4 and 2. (C) 2012 Elsevier Ltd.
