摘要Edible sea cucumbers are widely used as a health food and medicine. A fucosylated glycosaminoglycan (FG) was purified from the high-value sea cucumber Stichopus herrmanni. Its physicochemical properties and structure were analyzed and characterized by chemical and instrumental methods: Chemical analysis indicated that this FG with a molecular weight of similar to 64 kDa is composed of N-acetyl-D-galactosamin D-glucuronic acid (GlcA), and L-fucose. Structural analysis clarified that the FG contains the chondroitin sulfate E-like backbone, with-mostly 2,4-di-O-sulfated (85%) and some 3,4-di-O-sulfated (10%) and 4-O-sulfated (5%) fucose side chains that link to the C3 position of GlcA. This FG is structurally highly regular and homogeneous, differing from the FGs of other sea cucumbers, for its sulfation'patterns, are simpler. Biological activity assays indicated that it is a strong anticoagulant, inhibiting thrombin and intrinsic factor Xase. Out results expand the knowledge on structural types of FG and illustrate its biological activity as a functional food material.
