摘要：

A novel glycosaminoglycan-like sulfated polysaccharide (AAP) from the pleopods of Haliotis discus hannai Ino was purified by DEAE ion exchange chromatography followed with S-300 HR geltrion chromatography. Chemical composition analysis indicated that MP was composed of galactosamine, glucuronic acid, fucose, galactose with a ratio of 2.14:2.37:2.94:1, the content of sulfate was 15.5%. The average molecular weight (M-w) was 56.2 kDa in a TSK G4000 column. Further IR, 1D, 2D NMR spectroscopic analysis of the correlation signals of different sugar units gave a proposal repeating structure, as follows: [GRAPHICS] In vitro anticoagulant assay indicated AAP prolonged both the activated partial thromboplastin time (APT) and thrombin time (TT), with a 22.5 U/mg and 72.0 U/mg compared with standard heparin, respectively. The anticoagulant property of AAP was mainly attributed to powerful potentiation thrombin by anti-thrombin III. (C) 2011 Elsevier B.V. All rights reserved.
