Abstract:With the increasing deterioration of environmental factors such as air, water and oil, human health hazards are enormous. The world's first killer to human death – cancer can be often seen in our life and reasearch and development on anticancer drugs has been an important task in medical field. The foundation that chondroitin sulfate extracted from shark cartilage has a good efficacy against many diseases, which have high economic value, make the manner of how to improve industrial production of shark chondroitin sulfate and reduce production costs in the product yield cause wide attention in industry.
Through the combined method of Alkaline Hydrolysis and both enzymatic hydrolysis, the influence on extract’s nitrogen content of temperature, and pancreas enzyme increment can be detected. It is resulted that the lowest nitrogen content of chondroitin sulfate can be reached with the temprature of , of and pancreas enzyme increment of . This craft has mild response condition and little pollution, besides, it is easy to be pomoted. All of this make it have practical value in industrialized mass production.
Keywords：Sulfuric acid chondroitin; Extraction; Process Comparison
