摘要
本实验采用同时蒸馏萃取法(SDE)提取佩兰挥发性成分,测得佩兰挥发油的含量为2.73%,利用气相色谱-质谱(GC-MS)联用方法从佩兰挥发油中分离并确认出33种化学成分,用峰面积归一化法通过G1710BA化学站数据处理系统得出各化学成分在挥发油中的百分含量,其中主要成分为2H-1-苯并吡喃-2-酮(12.58%)、麝香草酚(4.38%)、2,4,5,6,7,8-羟基-1,4,9,9-四甲基-3H-3a,7桥亚甲基甘菊环(4.50%)、氧化石竹烯(5.27%)、1-甲基-4-(1-丙基)-酚(3.97%)、1,1a,4,5,6,7,7b,8-八氢-1,1,7,7a四甲基-2H-环丙基[a]萘-2-酮(3.62%)。
The essential oils of the Eupatorium fortunei Turcz. were extracted by simultaneous distillation extraction. The chemical components were separated and analyzed by gas chromatography-mass spectrometry. The content of essential oils extracted from Eupatorium fortunei Turcz. was 2.73%. The identification of the volatile compounds was confirmed by comparing the retention indices with standard values of authentic samples. The relative content was calculated from the peak area normalization method. The results indicated that there are thirty-three volatile compounds identified in Eupatorium fortunei Turcz. The major chemical components from Eupatorium fortunei Turcz. are： 2H-1-benzopyran-2-one（12.58%）, thymol （4.38%）,2,4,5,6,7, 8-hexahydro-1,4,9,9-tetramathyl-3H-3a,7-methanoazulene（4.50%）, caryophlleneoxidase（5.27%）, 1-methyl-4-（1-methylethyl）-phenol（3.97%） and 1,1a,4,5,6,7,7b-octahydro-1,1,7, 7a-tetramethyl-2H-cyclopropa[a]naphtha （3.62%）.
