A comparative study of antioxidant capacity of the fruits of different blueberry varieties
‘Britewell’,‘Bluemoon’,‘Cooper’,‘Berkeley’and ‘Brigitta’were analyzed in the fruits of five intro-duced blueberry varieties of in Hunan Forest Botanical Garden,the content of antioxidant substances such as soluble poly-saccharide,vitamin C,reduced glutathione and total anthocyanin were analyzed in the fruit,and DPPH free radical scav-enging ability and SOD activity were also measured. The correlative relationships among DPPH free radical scavenging ability and four antioxidants were analyzed. The results indicated that the vitamin C content,reduced glutathione content, totla anthocyanin content,DPPH free radical scavenging ability and SOD activity in‘Bluemoon’were significantly higher than that of other four cultivars (P<0.05 );DPPH free radical scavenging ability was significantly related with vitamin C content,reduced glutathione content and total anthocyanin content (P<0.05 );soluble polysaccharide content and DP-PH free radical scavenging ability weak correlation between ability.This study shows‘Bluemoon’has the highest antioxi-dant ability.
