What is chondroitin sulphate?

Chondroitin sulphate is a sulfated liner glycosaminoglycan extracted from cartilages of healthy animals such as bovine, porcine, avian and shark. It exists most commonly in the form of chondroitin sulphate sodium with content of chondroitin sulfate from 90% to 105% calculated on dry basis. Chondroitin Sulfate is included in both US Pharmacopoeia and European Pharmacopoeia and widely used in DietarySupplements as well as Drugs.

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

Chondroitin sulfate in 25KGS/drum
