气相色谱-质谱法研究藏药甘青青兰挥发油成分

Study on chemical constituents of the essential oil from Dracocephalum tangicum maxim by gas chromatography-mass spectrometry

采用水蒸气蒸馏法提取甘青青兰挥发油,用气相色谱-质谱法鉴定其化学成分和质量分数。甘青青兰挥发油主要成分为桉油醇(18.08%)、(1,α2α,5α)-2,6,6-三甲基二环[3.1.1]-3-庚酮(8.79%)、甲基环戊烷(4.22%)、芳樟醇(3.68%)、4-甲基-1-(1-甲乙基)-2-环己烯-1-醇(3.05%)等。

Essential oils were extracted from Dracocephalum tangicum Maxim by steam distillation （SD）. Their components were analyzed by gas chromatography-mass spectrometry （GC-MS）. 66 compounds were identified for the essential oil obtained by SD, and its main components have been found to be eucalyptol （18.08%）, Bicyclo[3.1.1 ] heptan-3-one,2,6,6-trimethyl-, （ 1α,2α, 5α. ）- （8.79%）, Cyclopentane, methyl-（4.22% ）, 1,6-Octadien-3-ol, 3, 7-di-methyl-（3.68% ）, 2-Cyclohexen-1-ol, 4-methyl-1-（ 1-methylethyl）-, （R）-（3.05%）.
