对25种干果的DPPH自由基清除活性和多酚含量进行了测定，并与鲜果进行了比较。还测定了抗坏血酸对该活性的贡献。所有干果均具有清除DPPH自由基的活性，其中山楂、杏和蓝莓的清除活性最高。其它带皮干果活性也较高。干果清除DPPH自由基能力与多酚含量呈高度相关。
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.
