85 results about "Euselachii" patented technology

Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus, as well as other Chondrichthyes such as the holocephalid eugenedontidans.

Method for extracting calcium chondroitin sulfate in shark cartilage

A method for extracting shark calcium chondroitin sulfate from a shark cartilage comprises the processes in sequence such as curing, alkalization, enzymatic hydrolysis, deproteinization, crystallization, resin pretreatment, resin exchange, ultrafiltration dehydration, calcification of filtrate and crystallization dehydration dying. Because secondary crystallization is adopted, the covalent binding of protein and shark chondroitin sulfate is broken by hydrogen peroxide to enable the chondroitin sulfate in the protein to be dissociated, impurities such as the protein and the like can be effectively removed to improve the purity and the content of shark sodium chondroitin sulfate; cation resin is adopted to complete the sodium removal process by column chromatography, the exchanged shark chondroitin sulfate is high in concentration and the shark chondroitin sulfate which is produced during ion exchange can be accurately controlled, and the sodium content in the product is low; with dehydration of ultrafiltration, not only the concentration can be realized, but also the small molecular impurities can be removed to improve the purity of the shark chondroitin sulfate, at the same time, to improve the content of calcium. The method also can save the using amount of ethanol and reduce the production cost.
