GC-MS 分析九头狮子草挥发油的化学成分

摘要

采用水蒸气蒸馏法提取九头狮子草挥发油,利用 GC-MS 联用技术,结合化学计量方法对其化学成分进行定性和定量分析,用面积归一法测定各组分的相对质量分数.结果表明：九头狮子草中挥发油主要由植酮(19．82％)、丁香油酚甲醚(3．96％)、β-石竹烯(3．75％)、肉豆蔻醚(3．08％)、3-甲基-2-(3,7,11-三甲基十二烷基)呋喃(3．64％)、2-戊基呋喃(2．73％)和氧化石竹烯(2．69％)等51种成分组成,占总量的98．82％.%The essential oils of Peristrophe japonica obtained by hydrodistillation from dried aerial parts of P .japon-ica ,were analyzed by gas chromatography-mass spectrometry(GC-MS).About 51 volatile components,consisting of 2-pentadecanone,6,10,14-trimethyl-(19.82%),eugenol methyl ether(3.96%),β-caryophyllene(3.75%),myristicin (3.08%),3-methyl-2-(3,7,11-trimethyldodecyl)furan(3.64%),furan,2-pentyl (2.73%)and caryophyllene oxide (2.69%),were identified on the basis of their mass spectral characteristics,comprising 98.82% of the total oil.
