Structural studies on a novel fucogalactan sulfate extracted from the brown seaweed Laminaria japonica

Antioxidant Properties of Polysaccharide from the Brown Seaweed Sargassum graminifolium (Turn.), and Its Effects on Calcium Oxalate Crystallization

“…Brown seaweeds have been used in traditional Chinese medicine for more than 1000 years [24]. Sargassum graminifolium , a brown seaweed extensively distributed along the coasts of the South China Sea and the East China Sea, is commonly consumed as seafood, and as medical resource for its antiallergic effects [25].…”

Further studies on structure of fucoidan from brown alga Saccharina gurjanovae

“…It was recently shown that brown alga S. latissima, along with others types of 278 polysaccharides, synthesized fucogalactan having a backbone of 6-linked β-D-galactopyranose 279 residues branched mainly at C-4 and containing both terminal galactose and fucose residues 280 (Bilan et al, 2010). Also, the structure of galactofucan from the brown alga S. japonica was A c c e p t e d M a n u s c r i p t 11 described (Wang et al, 2010). It is interesting to note, that the backbone of fucoidan contained 282 primarily 75% of (13)-and 25% of (14)-linked α-L-fucopyranose residues.…”

Structure and anticancer activity in vitro of sulfated galactofucan from brown alga Alaria angusta

“…Thus, (1 → 6)-type of linkage could not be excluded. Furthermore, (1 → 6)-type of linkages was found to be prevalent along galactofucans from S. japonica (Wang, Zhang, Zhang, Zhang, & Niu, 2010), S. latissima (Bilan et al, 2010) and Sargassum fuziforme (Li, Wei, Sun, & Xu, 2006). Negative-ion tandem ESIMS of monosulfated [GalFucSO 3 ] − ion at m/z 405.08 (see Supplementary materials) was also observed in mass spectra of recently studied C. costata (Anastyuk et al, 2012a) and S. gurjanovae (Shevchenko et al, 2015), where it was concluded that Gal-2-SO 3 − residue was, probably, terminal to the main backbone, built up of fucose residues.…”
