摘要
建立滁菊挥发性成分的全二维气相色谱/飞行时间质谱检测方法。通过使用全二维气相色谱/飞行时间质谱,以非极性柱Rxi-5MS(30m×0.25mm,0.2μm)作为第一维柱,中等极性柱Rxi-17(1.75m×0.1mm,0.1μm)作为第二维柱,对滁菊的挥发油成分进行定性分析。结合飞行时间质谱谱图库检索与全二维特有的包含结构信息的二维谱图,鉴定出滁菊的挥发性成分中相似度大于850的156种组分。
A method was established to determine volatile components in Chrysanthemum morifolium flowers using comprehensive two-dimensional gas chromatography (GC X GC) coupled with time-of-flight mass spectrometry (TOFMS). A non-polar column Rxi-5MS (30 m ×0.25 mm, 0.2μm) and a middle-polar column Rxi-17 (1.75 m × 0.1 mm, 0.1μm) were used as first and second dimensional columns, respectively. By TOFMS spectral library searching and comparison with unique comprehensive two-dimensional profiles with structural information, 156 volatile components with similarity of more than 850 were identified in this study.
