精油的一个馏分通常含有数百种化合物。尽管目前最先进的气相色谱（GC）和质谱（MS）仪器提供了技术改进和增强的选择性，但精油的复杂性经常被低估。采用二维气相色谱-飞行时间质谱联用技术（GC×GC-TOFMS）对依兰精油的化学成分进行了研究。基于这两个，增强的色谱分离和质谱去卷积，161个单独的化合物被确定和标记为潜在的特征分析物中发现的低和高沸点馏分从蒸馏成熟的依兰-依兰花。与最近的完整GC-MS表征相比，这代表了75种新化合物，主要由萜烯，萜类化合物酯和醇组成。
A single fraction of essential oil can often contain hundreds of compounds. Despite of the technical improvements and the enhanced selectivity currently offered by the state-of-the-art gas chromatography (GC) and mass spectrometry (MS) instruments, the complexity of essential oils is frequently underestimated. Comprehensive two-dimensional GC coupled to time-of-flight MS (GC×GC-TOFMS) was used to improve the chemical characterization of ylang-ylang essential oil fractions recently reported in a previous one-dimensional (1D) GC study. Based on both, the enhanced chromatographic separation and the mass spectral deconvolution, 161 individual compounds were identified and labeled as potentially characteristic analytes found in both low and high boiling fractions issued from distillation of mature ylang-ylang flowers. Compared to the most recent full GC-MS characterization, this represents 75 new compounds, essentially consisting of terpenes, terpenoid esters, and alcohols.
