摘要
采用同时蒸馏-萃取方法提取云南产牛蒡子的挥发油,并使用气相色谱-质谱联用仪分析其化学成分,该联用仪工作条件:载气流速1.0 m L/min;进样方式为分流进样,分流比20∶1,进样口温度为280℃;进样量为1μL;程序升温.然后通过计算机检索并结合谱图解析,鉴定了89个化合物的结构,占总挥发油的97.55%.质量分数超过10%的成分包括叶绿醇、2,4-癸二烯醛、环丁基胺和己醛.
The essential oil from Arctium lappa L. produced in Yunnan was extracted by simultaneous distillation extraction method and its chemical components were analyzed by Gas Chromatograph-mass spectrometry（ GC-MS） with which the working conditions are： the rate of the carrier gas was 1. 0 m L/min; the injection method was split-flow and the ratio of split-flow was 20 ∶ 1; the temperature of injection port was 280℃ and the sample size was 1 μL; the temperature of the programmed route increased. Then through computer retrieval with the spectrum analysis,the structures of 89 compounds were identified,taking up 97. 55% of the total contents. The mass fractions exceed ten percent including Phytol,2,4-Decadienal; Cyclobutylamine and Hexanal.
