<p>Heparin has been available for a long time as a naturally-occurring anticoagulant, and is now becoming increasingly inportant. A number of methods for isolating heparin from animal tissues such as the lungs, liver and intestinal mucus of pigs, cattle and sheep are known. According to the present invention, heparin is recovered from intestinal brine formed by treatment, with aqueous sodium chloride solution or solid sodium chloride in the presence of water, of animal intestines from which intestinal mucus has been removed. The heparin recovered is almost completely free of byproducts and heparin of good quality is obtained.</p> |
