Abstract
The present invention provides a fucoidan-derived low molecular weight compound with a good quality of taste, which has a specified structure and function and is free from problems in absorption, antigenicity, uniformity, an anticoagulant activity and so on, which problems arise when developing fucoidan, a sulfated polysaccharide having an extremely large molecular weight, as drugs or health foods. As a result of analyzing low molecular weight compounds obtained by acid hydrolysis of fucoidan, the inventors have identified fucoidan oligosaccharides (I) to (XI). Further, these oligosaccharides have been found to have anti-obesity and/or blood glucose elevation suppressing effects through inhibition of carbohydrate and/or lipid absorption as a result of α-glucosidase inhibition and/or lipase inhibition.
