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%)。

Abstract: 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 normal-ization 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%).
