Abstract
Pomegranate is one of the major sources of polyphenoles and anthocyanins,which reveal high antioxidant activity.The contents of total anthocyanins and total polyphenols in pomegranate from 5 main varieties in China were determined,and their antioxidant activity was assessed by DPPH and ABTS radical scavenging assays,FRAP assay,ferrous ion-chelating assay..The contents of total anthocyanins and total polyphenols were in the range of 3.54-13.89 mg/100 g and 38.89-68.28 mg/100 g fresh pomegranate arils,respectively.The scavenging rates against DPPH and ABTS radicals were 24.30%-45.73% and 58.02%-83.40%,respectively,the results of FRAP assay 0.38-0.78,and the results of ferrous ion-chelating assay 14.73%-70.60%.Of the cultivars investigated,Kashen red seed sour pomegranate had the most powerful antioxidant activity followed by Yu pomegranate.关键词
