气相色谱飞行时间质谱法分析不同产地洋甘菊油的挥发性成分

采用气相色谱-飞行时间质谱（GC-TOF/MS）联用技术测定了不同产地洋甘菊油的挥发性成分,并通过质谱库检索,结合保留指数比对,从法国、德国和英国三个产地的洋甘菊油中分别鉴定出65、70和53种挥发性成分,分别占总峰面积的85.06%、96.70%和89.85%。三个产地洋甘菊油的挥发性成分在数量及含量上有一定的差异,并对其特征致香物质的香气进行了分析。建立了洋甘菊中的多种挥发性成分的分析方法。该研究为洋甘菊油制定科学的质量标准以及合理开发利用提供初步实验依据。 

Analysis of volatile components in chamomile oil form different producing areas by GC-TOF/MS

The volatile components of chamomile oil form different producing areas were analyzed by using of gas chromatography-time-of-flight mass spectrometry(GC-TOF/MS). With the mass spectrometry library search,65,70 and 53 volatile components were identified by using retention index from chamomile oil that were produced in France,Germany and the United Kingdom,representing 85.06%,96.70% and 89.85% of the total volatile components. There were certain differences in the kinds and content of volatile components in France,Germany and Roman. The aroma of characteristic volatile components of chamomile oil was analyzed. A method for quantitative determination of volatile components in chamomile oil was established. The results provided technical support for the development and application of chamomile oil.
