摘　　要：本文以8个不同生姜品种的根茎为试验材料,利用DPPH法、水杨酸法、邻苯三酚自氧化法、金属鳌合离子法测定其抗氧化性,最后利用隶属函数分析法进行综合评价。结果表明:供试8个生姜品种都有较强的抗氧化能力;利用不同方法测定不同生姜品种的抗氧化性结果不尽相同,其中DPPH清除率以冀姜18最高,为91.78%,安徽铜陵大姜最低,为70.93%;羟自由基清除率以冀姜5最高,为85.02%,冀姜7最低,为71.89%;超氧阴离子清除率中最高的是冀姜5,为46.239%,最低的是冀姜1,为20.647%;金属离子鳌合率最高的是安徽铜陵大姜59.87%,最低的是冀姜1,为12.50%。通过隶属函数法进行综合评价发现,8种生姜品种的综合抗氧化活性顺序由强到弱依次为:冀姜5、山东昌邑大姜、山东娃娃姜、冀姜2、安徽铜陵大姜、冀姜18、冀姜7、冀姜1。Materialed with 8 different varieties of Zingiber officinale Rosc.,the antioxidant properties were determined by DPPH,salicylic acid,phthalic three-phenol autoxidation and metal chelating ion.Finally,the membership function analysis method was used to make a comprehensive evaluation.The results showed that all the 8 varieties had strong antioxidant capacity.The results of different methods for determining the antioxidant properties of different ginger varieties were not the same.The highest DPPH scavenging rate was91.78% in ＂Jijiang 18＂,and 70.93% in ＂Anhui Tongling＂.The scavenging rate of hydroxyl radical was 85.02%in ＂Jijiang 5＂ and 71.89% in ＂Jijiang 7＂.The highest scavenging rate of superoxide anion was ＂Jijiang 5＂,（46.239%）,and the lowest was ＂Jijiang 1＂,（20.647%）.The highest metal ion chelation rate was 59.87 in ＂Anhui Tongling＂,and the lowest was ＂Jijiang 1＂,（12.50%）.The comprehensive evaluation of the membership function method showed that the order of the comprehensive antioxidant activity of the 8 varieties was as follows：＂Jijiang 5＂〉 ＂Changyi big ginger＂ 〉＂Shandong Wawa ginger＂〉 ＂Jijiang 2＂ 〉＂Anhui Tongling＂ big ginger 〉＂Jijiang 18＂ 〉＂Jijiang 7＂ 〉＂Jijiang 1＂.
