  The chromatogram of the enzymatically digested sample solution as obtained in the test for the limit of nonspecific disaccharides shows three main peaks corresponding to △DI-4S, △DI-6S,△DI-OS in the enzymatically digested standard solution. By peak area response, △ DI-4S is the most abundant, followed by the △ DI-6S, with △ DI-OS being the least abundant of the three

Production Flow Chart of Marine Chondroitin Sulfate


Marine Cartilages


Pre-treatment(cartilages selecting and washing)                    


Boiling ( add NACL,boil for 5 hours at the temperature of 90℃)


Enzymolysis (add pancreatin, add NAOH to adjust the PH value to 8.5-9.0, boil for 6 hours at the temperature of 48℃-50℃





First sedimentation(add ethanol to dissolve out the crude chondroitin sulfate)


Hydrolysis (add water and NACL,add NAOH to adjust PH value to about 9.0. Adjust temperature to 48℃-50℃




Second sedimentation(add ethanol to dissolve out purified chondroitin sulfate



Dehydration (add ethanol to dehydrate the water out of chondroitin sulfate



Centrifugation (get rid of ethanol)





Milling and Sifting


Blending (No other materials are added, just mixing)


Packing and testing
