摘要:

采用气相色谱- 质谱(GC-MS)法分离测定丁香(ECT)和桂皮(CCP)挥发油及其混合物(ECT+CCP)成分,利用化学计量学解析法对重叠的色谱峰进行解析,得到各组分的纯色谱曲线和质谱,通过质谱库对解析的纯组分进行定性,丁香和桂皮挥发油及其混合物的定性分析结果分别为23、29 和34 个组分,占总含量的99.32%、96.38%、97.20%。结果表明,丁香与桂皮挥发油混合后发生了复合效应,有两个新组分生成;化学组分种类基本上为两个单味香料的加和,其组分主要来自于桂皮;单味香料挥发油组分的含量在混合后发生了变化,丁香组分含量在混合油中较高。

Abstract:

Gas chromatography-mass spectrometry (GC-MS) coupled with chemometric resolution upon two-dimensional data was employed as a method for the analysis of volatile components in a traditional Chinese volatile oil of flavor pair clove (ECT), cassia Bark (CCP), and mixed oil of the above two kinds of oil. Totally 23, 29 and 34 volatile components in essential oil of ECT , CCP, and ECT+CCP were respectively qualified and quantified, accounting for 99.32%,96.38%, and 97.20% of total essential oil of ECT, CCP, and ECT+CCP, respectively. The experimental results showed that the number of volatile components in ECT+CCP were mainly from those of CCP, and was almost equal to the sum of volatile components in ECT or CCP oil. However, two new components, i.e., ylangene , bicyclo[3.1.1]hept-2-ene, 2,6-dimethyl-6-(4-methyl-3-pentenyl)-, were found in ECT+CCP oil due to chemical reactions during the mixture process. The relative contents of volatile components from Clove were higher than those from Cassia Bark in mixed volatile oil.

Key words: clove, cassia bark, essential oil, gas chromatography-mass spectrometry (GC-MS), chemometric resolution method
