摘　　要：目的:探究茉莉花叶甲醇提取物的体外抗氧化活性,为充分利用茉莉花资源提供理论依据。方法:通过分光光度法测定茉莉花叶甲醇提取物清除超氧自由基(O-2·)和1,1-二苯基-2-三硝基苯肼自由(DPPH·)能力,普鲁士兰法测定其还原Fe3+能力,从而研究茉莉花叶甲醇提取物的体外抗氧化活性。结果:茉莉花叶甲醇提取物具有较强的清除O-2·和DPPH·自由基能力,并能还原Fe3+。结论:茉莉花叶甲醇提取物具有较强抗氧化作用,在一定浓度范围内,其抗氧化性随着浓度的增大而增强。Objective ： To study antioxidant activity in vitro of methanol extract of the leaves of Jasminum sambac, and provide the theory to make use of the Jasmine resources. Methods：The scavenging effect of the methanol extracts of the leaves of Jasminum sambac on O2- · and DPPH · were assayed by spectrophotometry. The ability of reducing Fe3＋ was detected with Prussia method . And study of antioxidant activity in vitro of methanol extract of the leaves of Jasminum sambac. Results ： The methanol extract of the leaves of Jasminum sambac had a strong scavenging ability for O2 - · and DPPH · and had a strong reduction ability for Fe3 ＋. Conclusion ： The methanol extract of the leaves of Jasminum sambac had strong antioxidative effect, in a certain range of concentration, its antioxidant activity increases with increasing concentration.
