| Summary: | Sulfated polysaccharide is an important nutritional component in shellfishes. In this study, a rapid microextraction and purification process for sulfated polysaccharides from marine shellfishes was established and applied to nine different shellfishes. Types of glycosaminoglycans (GAGs) from nine species of edible shellfishes were qualitatively analyzed by their basic chemical components, molecular weights and monosaccharide compositions. The results showed that the method could rapidly separate and purify polysaccharides. The purified polysaccharides were single components with molecular weights ranging from 24 to 55 kDa. Analysis of monosaccharide composition and infra-red spectra results showed that sulfated polysaccharides had GAGs-like properties. The polysaccharide samples from Buccinidae and Trichomya exhibited the characteristics of chondroitin sulfate (CS), which were represented by Buccinum pemphigum and Perna viridis. The polysaccharide samples from Argopecten irradians showed heparin (HP) characteristics. This study provides a micro- and rapid pretreatment technology for the structural analysis of sulfated polysaccharides from edible shellfishes. |
