The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity and polyphenol content of 25 dried fruits were evaluated and compared with fresh fruits. The contribution of ascorbic acid to this activity was also determined. All dried fruits contained DPPH radical-scavenging activity with hawthorn, apricot and blueberry having the highest. Other dried fruits containing rind also had high activity. The DPPH radical-scavenging activity and polyphenol content of dried fruits were highly correlated.
