以鸡胸软骨为原料提取硫酸软骨素的研究

摘要

以鸡胸软骨为原料,在60℃下用木瓜蛋白酶水解除去蛋白质,再用乙醇沉淀获得鸡胸软骨多糖.色谱分析和聚丙烯酰胺凝胶电泳鉴别显示,鸡胸软骨多糖主要是硫酸软骨素,表明鸡胸软骨是可行的硫酸软骨素新来源.%With chicken keel cartilage as raw material,the polysaccharides of chicken keel cartilage was obtained by removing protein by hydrolysis with papain and precipitation with ethanol.Chromatographic analysis and polyacrylamide gel electrophoresis showed that chondroitin sulfate was the main component of polysaccharides of chicken keel cartilage.The chicken keel cartilage is an available new source of chondroitin sulfate.
