球等鞭金藻胞外多糖的体外抗氧化活性和理化性质的初步分析
Study of in vitro antioxidation and physical and chemical characteristics analysis of extracellular polysaccharides iso-lated from Isochrysis galbana
摘要
Abstract
The extracellular polysaccharides, ECPSⅢ, has been successfully isolated from marine microalgae Isochrysis galbana through a combination of anion-exchange column chromatography and repeated gel chromatog-raphy in previous study. Its in vitro antioxidant activities and physical and chemical properties were investigated. The results showed that ECPSⅢ has good antioxidant activities and perticularly it has relative stronger scavenging activities against superoxide radical and hydroxyl radical. ECPSⅢ is a acidic polysaccharide rich in sulfuric acid radicals and uronic acid. The contents of sulfuric acid radicals and uronic acid were 76.90 mg/g and 17.1%in ECPSⅢ, respectively.关键词
