[Isolation of heparin and chondroitin sulfate from animal tissue by an ion exchange method].

Isolation of mucopolysaccharides (heparin and chondroitin sulfate), from animal tissue by ion exchange was studied. The yields of heparin and chondroitin sulfate of up to 20,000-150,000 units/kg and 14 g/kg, respectively, can be obtained depending of the type of the raw material used and the sorbent, which absorbs heparin and chondroitin sulfate from aqueous solutions in amounts of 100-250 mg per g sorbent. Ion-exchange sorption of mucopolysaccharides on synthetic sorbents permits extracting fractions of these compounds with the maximum biological activity.
