Oligosaccharide derived from fucoidan

Fucoidan pharmaceutical molecular weight is very large sulfated polysaccharide, resulting in the development as a health food, the absorption of fucoidan, antigenicity, uniformity, eliminate the problems with anticoagulant activity, etc., and the taste quality has been to provide a fucoidan derived from low-molecular compound having a function as specified structure. By analyzing the low molecular compound obtained by acid hydrolysis of fucoidan was identified fucoidan oligosaccharide (I) ~ (XII). Furthermore, it was found that in these oligosaccharides is preventing obesity, blood sugar increase inhibitory effect by inhibiting the absorption of carbohydrates and lipids by α- glucosidase inhibiting or lipase inhibition.
