摘　　要：首次采用气相色谱-质谱联用(GC-MS)分析小叶女贞果实挥发油化学成分,并以ABTS自由基和亚硝酸钠清除作用评价25%挥发油抗氧化活性。从小叶女贞果实挥发油中共鉴定出67种化合物,占挥发油总量的76.50%,主要成分有大根香叶烯D(8.57%)、顺式-2-反式-6-金合欢醇(6.38%)、α-荜澄茄烯(5.24%)、2-己烯醛(3.80%)、芳樟醇(3.78%)、α-衣兰油烯(3.70%)等。挥发油对ABTS自由基和亚硝酸钠具有明显地清除作用,样品量与清除率间呈量效关系。In this study, the chemical consituents of volatile oil of Ligustrum quihoui fruits were determined by gas chro-matography-mass spectrometry （GC-MS） for the first time and the antioxidant activity of 25% volatile oil was investiga-ted by evaluating its scavenging capacity against ABTS · and sodium nitrite. Sixty-seven compounds ,which occupied 76. 50% of total constituents ,were tentatively identified. The major constituents of the volatile oil were germacrene D （8. 57% ）, cis-2-trans-6-famesol （6.38%）, α-eubebene （5.24%）, hex-2-enal （3.80%）, linalool （ 3.78% ）, α-muur-olene （3.70%）. The volatile oil exhibited significant scavenging capacities against ABTS ·and sodium nitrite in a con- centration-dependent manner.
