Isolation, chemical investigation and antiviral activity of polysaccharides from Gracilaria corticata (Gracilariaceae, Rhodophyta)

open access: yesInternational Journal of Biological Macromolecules, 2002
Polysaccharides were sequentially extracted from the agarophyte Gracilaria corticata. Chemical analysis combined with infrared spectroscopy showed that the cold water extracted material consists mainly of a high molecular weight sulfated galactan. Most of the sulfate groups are alkali labile and are located at C-4 of the 1,3-linked D-galactose units ...
