Abstract
Objective To determine the component sugars, the molecular weight, the forms of linkage and scavenging action to hydroxyl free radical of GBL( Ginkgo biloba leaf) polysaccharide. Methods The component sugar was determined by gas chromatography analysis. Its molecular weight was measured by gel filtration. The scavenging action to hydroxyl free radical was tested by Fenton reaction contrasting with special eliminations for hydroxyl free radicals, for example, mannitol,benzoic acid. Results The polysaccharide was composed of rhamnose, arabinose, mannose and galactose. Its mean molecular weight was estimated to be The scavenging action to hydroxyl free radical was represented by the content scavenging 50% of all hydroxyl free radical The of polysaccharide, mannitol, and benzoic acid was 867,3996 and 490μg/ml. Conclusion The polysaccharide is a heteropolysaccharide, its main chain is composed of a-linkage. It has a scavenging action to hydroxyl free radical by Fenton reaction.关键词
