摘　　要：对稠李属3种果实浸提得到的花色苷抗氧化活性进行了比较。采用羟自由基(.OH)清除能力、ABTS自由基清除能力、DPPH自由基清除能力、总还原能力来评价稠李属3种果实花色苷的抗氧化活性,并采用VC作对照。结果表明:稠李属3种果实的花色苷对.OH、ABTS、DPPH有较强的清除能力,且抗氧化活性均随样品浓度升高而增强,呈明显的量效关系,在试选范围内清除效果均低于VC对照组。但当稠李及山桃稠李的质量浓度大于0.04 mg/mL时,其还原能力强于VC对照组。3种果实花色苷中,抗氧化活性从大到小依次为稠李>山桃稠李>紫叶稠李。The antioxidant activity of anthocyanins which were extracted from three kinds of Padus Mill fruits was researched and compared.The antioxidant activity was evaluated by the abilities to scavenging ·OH free radical,ABTS free radical,DPPH free radical and the total reduction capacity,and then compared with Vc.The result showed that the three kinds of anthocyanins possessed remarkable scavenging effects against ·OH free radical,ABTS free radical and DPPH free radical.The antioxidant activity increased with the concentration increasing and showed a obvious does-effect relationship.The scavenging effect of the three kinds of anthocyanins was lower than Vc control group in the selected concentration range,but the reduction capacity of Padus racemosa and Prunus maackii was stronger than the control group when the sample concentration was more than 0.04mg/ml.Comparing the anthocyanins of the three kinds fruits,the order of antioxidant activity was Padus racemosa Prunus maackii Padus virginiana.
