| 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%。 |

| Abstract: |
| The essential oils of Peristrophe japonica obtained by hydrodistillation from dried aerial parts of P. japonica,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. |
