Abstract:
Soluble crude polysaccharide form Pleurotus eryngii were extracted by the method of constant temperature water bath shaking,and solid polysaccharide of Pleurotus eryngii was isolated and purified.Using scavenging percentage of polysaccharide of Pleurotus eryngii to oxygen free radical as index,scavenging activity was determined with pyrogallol autoxidation method and phenanthroline-Fe2+ reaction system.The results showed that polysaccharide of  Pleurotus eryngii had significant effect on scavenging hydroxyl radicals and super oxide anion radicals.The scavenging activity of polysaccharide of Pleurotus eryngii clearance both superoxide anion radicaland hydroxyl radical increased with the rise of polysaccharide concentration at a certain range,and there was a good linear relationship.When the concentration of polysaccharide was 0.7 mg/mL,the percentage of scavenging hydroxyl radicals could reach 98.65%,and the percentage of scavenging super oxide anion radicals was 37.66%.
