摘要: 采用水蒸气蒸馏法提取樗叶花椒树皮精油,气相色谱-质谱联用法分离并分析鉴定其成分及相对含量,并研究了精油的抗氧化活性。结果表明,在樗叶花椒树皮精油中共鉴定出54个化合物,樗叶花椒树皮中精油的主要成分为(-)-松油烯醇(17.64%)、桉叶醇(13.82%)、香桧烯(11.73%)、γ-萜品烯(10.88%)、α-蒈烯(8.00%)、芳樟醇(6.93%)、萜品油烯(5.86%)、α-萜品醇(4.44%)、(-)-α-水芹烯 (2.25%)等;400 ppm的樗叶花椒树皮中精油对超氧阴离子自由基(O2·)、羟基自由基(·OH)、有机自由基(DPPH·)以及体外模拟胃液中亚硝酸根离子(NO2-)的清除率分别达到17.4%、49.1%、48.7%和50.8%。

Abstract: The chemical composition of the steam distillated essential oil obtained from twigs bark of Zanthoxylum ailanthoides was analyzed by gas chromatography-mass spectrometry (GC-MS),and antioxidant activities of the essential oil were analyzed. GC-MS analysis of the oil resulted in determination of 54 compounds. (-)-terpinen-4-ol (17.64%), eucalyptol(13.82%), sabinene (11.73%), γ-terpinene (10.88%), α-carene(8.00%), linalool(6.93%), terpinolene (5.86%), α-terpineol(4.44%) and (-)-α-phellandrene(2.25%) were determined as the major components.The inhibition percentages of superoxide anion free radical(O2·),hydroxyl free radical(·OH),DPPH radical and eliminating NO2- (scavenging activity) of the essential oil(400 ppm) were 17.4%,49.1%,48.7% and 50.8%,respectively.
