英文摘要	The crude polysaccharide (HFS) from Sargassum fusiforme (Hizikia fusiforme) was extracted using 0.1 M HCl and was fractionated by anion-exchange chromatography into three fractions: HFS-1, HFS-2, and HFS-3. Based on the chemical analysis, HFS-1 was composed of laminaran, HFS-2 was a mixture of alginate and sulfated heteropolysaccharides, and HFS-3 was primarily composed of sulfated galactofucan. The NMR spectra revealed that HFS-1 was composed of a soluble laminaran with chains that are terminated by beta-D-glucose residues. In contrast, the spectra obtained for HFS-2 were still complex, even after most of the alginate was removed. In addition, HFS-3 might contain 3-linked fucan sulfated at C-2, 6-linked galactan sulfated at C-2 and branched at C-4 by 2-sulfated Fuc, and galactofucan with a backbone of either alternating Gal and Fuc sulfated at C-2 or alternating (Gal)(n) and (Fuc)(n) sulfated at C-2. Moreover, HFS-3 also contained small amounts of fucoglucuronomannan and xylan. (C) 2013 Elsevier Ltd. All rights reserved.
