The differences in composition and properties of crude chondroitin sulfate preparations obtained by the alkaline liquefaction method (A-CCS) and the Pronase digestion method (E-CCS) were studies and the following results were obtained. 1) Both A-CCS and E-CCS contained mainly chondroitin sulfate A and a small amount of chondroitin sulfate C, keratosulfate and hyaluronic acid. 2) A-CCS contained less keratosulfate and protein than E-CCS, and the molecular weight of A-CCS was half that of E-CCS. 3) By fractional precipitation of A-CCS with ethanol, chondroitin sulfate which was slightly contaminated with keratosulfate sand hyaluronic acid was obtained in about 70% yield. 4) A-CCS was stronger than E-CCS in antioxidative action on vitamin C and weaker in protective action on colloid.
