摘要: 采用同时蒸馏萃取(SDE)法提取东北连翘鲜花精油,气相色谱-质谱法(GC-MS)分析精油的化学组分,考察不同溶剂对结果的影响。结果表明,SDE石油醚萃取得到的东北连翘鲜花精油得率为0.69%,鉴定得到28种成分,GC含量最高的化合物为二十五烷(28.65%),其次是Z-9-二十三烯(27.82%)。SDE正己烷萃取得到的东北连翘鲜花精油得率为0.81%,鉴定得到44种成分,GC含量最高的化合物为Z-9-二十三烯(47.16%),其他香料化合物如肉豆蔻醛(0.97%)、石竹烯(0.05%)等。两种精油的共有成分Z-9-二十三烯可用作家蝇性引诱剂。

Abstract: Essential oils of Forsythia mandschurica Uyeki fresh flowers were extracted by simultaneous distillation extraction(SDE) method. Chemical composition of essential oils were analysized by gas chromatography-mass spectrometry(GC-MS). The effects of different solvents on the results were studied. The results showed that the yield of essential oil of F. mandschurica Uyeki fresh flower extracted by SDE light petroleum method was 0.69%.28 components were identified from it. The highest GC content compound was pentacosane(28.65%), and the second was Z-9-tricosene(27.82%). The yield of essential oil of F. mandschurica Uyeki fresh flower extracted by SDE hexane method was 0.81%.44 components were identified from it. The highest GC content compounds was Z-9-tricosene(47.16%). The Z-9-tricosene was housefly sex attractant, and other aromatic compounds were myristic aldehyde(0.97%), caryophyllene(0.05%), etc.
