为了鉴定评价出小豆资源抗氧化性高的品种，通过测定小豆的总抗氧化能力和羟自由基清除能力，研究来源于不同地区不同颜色的181个小豆品种的抗氧化性。结果表明，粒色，百粒重和所在地区对小豆抗氧化性有不同程度的影响。通过实验研究最终得出，绿色小豆总抗氧化性最高，黄白颜色次之，红色最低；百粒重与抗氧化性成反比，百粒重越大，抗氧化能力越弱，反之则越大；对其中156个红小豆品种进行比较，东北辽宁地区的红小豆品种总抗氧化能力最高，日本最低，但日本品种的羟自由基清除能力很高。

In order to assess and evaluate beans with high antioxidant by measuring total antioxidant capacities and the hydroxyl radical scavenging activities of Adzuki Beans, studied 181 kinds of Adzuki beans from various area and various color. The result showed that, the color of surface, the weight of 100 beans and the beans, areas were the main factors of infecting Adzuki beans, antioxidant capability during analyzing. The green beans had the highest total antioxidant, yellow and white beans had the second, red beans had the lowest. The weight of 100 beans was in an inverse ratio of the antioxidant, if the weight of 100 beans was high, the antioxidant was low; compare total antioxidant capacities and the hydroxyl radical scavenging activities of 156 kinds of red beans, the kinds with the highest of total antioxidant capacity were from Liaoning which lies in northeast of China, and the lowest was from Japan, but the red beans from Japan had higher hydroxyl radical scavenging activities.
