本文报道用气相色谱法,选用OV-101弹性石英毛细管柱,长26m,内径0.2mm,载气线速度19.7cm/s,分流比:1/100,柱温70°—190℃线性程序升温每分钟2℃,分离独活挥发油,得107个色谱峰。经毛细管色谱-质谱-计算机联用(GC-MS-DS)测定辅以色谱标准品对照定性方法,从独活油中鉴定出21种成分。主要成分为:正辛烷、4-甲基环已酮、2-甲基辛烷、正壬烷、(?)-蒎烯、(?)-萜品烯、3-甲基壬烷、β-蒎烯,月桂烯、(?)-水芹烯、蒈烯、对繖花烃、枞油烯、正十一烷、桃金娘烯醛、对甲氧基乙酰苯、1-异丙基-4-亚甲基-7-甲基-1、2,3,4,4A、5,6,8A,八氢化萘、胡椒烯、榄香烯、橙花叔醇及愈创木醇。
This paper reports the use of gas chromatography, selected OV-101 elastic quartz capillary column, length 26m, diameter 0.2mm, carrier gas velocity 19.7cm / s, split ratio: 1/100, column temperature 70 ° -190 °C linear program temperature rise per At a temperature of 2°C, separate volatile oils were obtained and 107 peaks were obtained. A total of 21 components were identified from Duhuo Oil by capillary chromatography-mass spectrometry-mass spectrometry (GC-MS-DS) coupled with a chromatographic standard qualitative method. The main components are: n-octane, 4-methylcyclohexanone, 2-methyloctane, n-decane, (?)-pinene, (?)-terpinene, 3-methylnonane, ? - Terpene, myrcene, (?)-phellandrene, terpene, p-cymene, decylene, n-undecane, myrtonaldehyde, p-methoxyacetophenone, 1-isopropyl -4-methylene-7-methyl-1,2,3,4,4A,5,6,8A, octahydronaphthalene, piperonyl, elemene, nerolidol and guaiacol.
