石参多糖的体外抗氧化活性研究
Study on antioxidant effect of polysaccharide from Shishen（Eremurus chinensis） in vitro
摘要
Abstract
The polysaccharides from Shishen（Eremurus chinensis）were obtained through water extracting and ethanol precipitating method.Clearance rate of the polysaccharides to hydroxyl radical（·OH）,superoxide anion（O-2·）,hydrogen peroxide（H2O2）and 2,2-Diphenyl-2-picrylhydrazyl（DPPH·）was determined by UV method,and compared with VC.Then the antioxidant effects of polysaccharides were studied.The results showed the polysaccharide had certain antioxidant capacity through comparing with positive control VC.The polysaccharide had stronger capacity of scavenging on the H2O2 and had different scavenging activity on the DPPH·,·OH and O-2·.It was indicted to a positive correlation with concentration of polysaccharides.关键词
