探索一种新的硫酸软骨素来源。以秘鲁巨鱿软骨为原料，经过酶解、超滤浓缩和乙醇沉淀的方法获得硫酸软骨素。秘鲁巨鱿硫酸软骨素得率为3.2%，比旋度为-25.2°，黏均分子量为157000，硫酸软骨素E型二糖占总二糖比例的17%。秘鲁巨鱿软骨可以作为一种硫酸软骨素新原料。%The arm of this research was to explore a new sources of chondroitin sulfate. With the purification process of enzymolysis,filtration and ethanol precipitation,chondroitin sulfate(CS) was purified from the carti-lage of Dosidicus gigas and characterized in an effort to find alternative source. The yield of CS was about 3.2%, the specific rotation was-25.2°,viscosity-average molecular was 157 000,the E-type disulfated disaccharides was 17%in all CS extracts. The Dosidicus gigas cartilage can be used as a new source of CS.
