arbutus pigment%extraction%antioxidant activity
比较了浸提法、热煮法、粉碎法等3种方法提取杨梅色素苷的提取量，并对其抗氧化性能进行了研究。结果表明：浸提法提取效果最好，在510 nm处的吸光度为0.198，而粉碎法为0.054；杨梅色素苷浓度与其抗氧化能力、超氧阴离子自由基及羟基自由基的清除能力之间存在明显正相关，当杨梅色素苷浓度为34 mg·mL-1时，其对超氧阴离子自由基的清除率达到80％；相同浓度下杨梅色素苷的还原力高于抗坏血酸。

The extraction amounts of arbutus pigment by leaching method,cooking method and grinding method were compared.The antioxidant activity of arbutus pigment was studied.Results showed that the leac-hing method was the most effective extraction method with the absorption value of 0.198 at 510 nm,while the grinding method was 0.054.There were obviously positive correlations between arbutus pigment concentration and antioxidant capacity,superoxide anion radical scavenging capacity,hydroxyl radical scavenging capacity. When arbutus pigment concentration was 34 mg·mL-1 ,the scavenging rate of superoxide anion radical reached 80%.The reduction ability of arbutus pigment was higher than that of ascorbic acid at the same concentration.
