摘　　要：采用水蒸气蒸馏法提取黑龙江产万寿菊叶精油,通过单因素和正交试验,研究万寿菊叶精油提取的最佳工艺条件。结果表明:最佳工艺条件为料液比1:6、蒸馏时间5h、加热温度110℃,此条件下精油的产率为0.0944%。采用气相色谱-质谱法对精油的化学成分进行分析,共分离出31个峰,鉴定出其中的29个化合物,占总峰面积的93.55%。主要成分有异松油烯(37.02%)、2-异丙基-5-甲基-3-环己烯-1-酮(14.08%)、柠檬烯(13.08%)、β-罗勒烯(8.78%)、石竹烯(4.18%)。The steam distillation extraction of essential oil from African marigold leaves was optimized for achieving maximum oil yield using single factor and orthogonal array design methods,and chemical composition analysis of the extracted oil was carried out using gas chromatography-mass spectrometry（GC-MS）.The optimal conditions for oil extraction were found as follows：material-liquid ratio 1：6;distillation duration 5 h;and heating temperature 110 ℃,and the resultant oil yield was up to 0.0944%.The GC-MS analysis showed that 31 peaks were separated,and 29 of them were identified,accounting for 93.55% of the total peak area,and the main components were cyclohexene（37.02%）,2-isopropyl-5-methyl-3-cyclohexen-1-one（14.08%）,limonene（13.08%）,3,7-dimethyl-1,3,6-octatriene（8.785%） and caryophyllene（4.18%）.
