摘　　要：目的研究小叶丁香枝不同部位在四种评价体系下的体外抗氧化活性。方法采用清除DPPH·、ABTS+·评价法、还原性测定法和总酚含量测定方法 ,利用UV测定小叶丁香枝不同部位抗氧化能力和总酚含量。结果小叶丁香枝不同部位抗氧化活性的强弱顺序为:乙酸乙酯部位>正丁醇部位>总提液>氯仿部位>石油醚部位,且随着各部位浓度的增加,抗氧化能力呈现良好的量效关系。结论:小叶丁香枝抗氧化能力较好,乙酸乙酯部位、正丁醇部位较好,表明其可能是潜在来源的天然抗氧化剂,也为将来寻找活性化合物指明了方向。objective： Study on antioxidant activities of different extracts from the branch of Syringa pubescens Turcz in four kinds of evaluation system. Methods： Using DPPH radical scavenging method,ABTS radical scavenging method,reducing power measuration and total phenols content determination method to evaluate the antioxidant activity and determine total phenolic content of different extracts by spectrophotometer. Results： The order of antioxidant activities of different extracts from the branch of Syringa pubescens Turcz was：ethyl acetate extract〉normal butanol extract〉total solution〉 chloroform extract 〉petroleum ether extract. With the higher the concentration of different concentration extract, the antioxidant ability exhibited well dose-response relationship.Conclusion： Syringa pubescens Turcz exhibited significant antioxidant properties, itls ethyl acetate extract and normal butanol extract showed well, it suggest that they may be the potential source of nature antioxidant, aslo it point to the direction of finding active compound in the future.
