Fucoidan, a special intercellular polysaccharide, which exists in the cell wall matrix, is the unique biological activity matter in brown algae.

We extract the fucoidan from the Laminaria japonicia. The product,which is hydrosoluble heteropolysaccharide, mainly consists of sulfuric ester- Fucose, and also have little quantities of galactose, Mannose, xylose, arabinose, saccharic-aldehyded acid. So it’s also called algin or fucoidan & laminaran, the major effective ingredient is α-L-fucose-4-sulfuric ester.
