溶剂萃取/溶剂辅助风味蒸发-气相色谱/质谱联用分析野韭菜花挥发性成分

摘要

The essential oil in fresh flowers of wild Chinese chive was extracted by solvent extraction/solvent-assisted flavor evaporation（SE/SAFE） and analyzed by gas chromatography-mass spectrometry（GC-MS） carried out on the non-polar capillary column RTX-5 and the polar capillary column DB-WAX,respectively based on retention index（RI）.Totally 47 compounds were identified,including 28 sulfur-containing compounds,4 aldehydes,3 alcohols,3 ketones and 9 hydrocarbons.The major volatiles of fresh flowers of wild Chinese chive were sulfur-containing compounds.%以乙醚为溶剂,采用溶剂萃取/溶剂辅助风味蒸发法（solvent extraction/solvent-assisted flavor evaporation,SE/SAFE）提取新鲜野韭菜花精油,采用气相色谱-质谱联用（gas chromatography/mass spectrometry,GC-MS）法结合双柱（RTX-5色谱柱和DB-WAX色谱柱）保留指数（retention index,RI）定性分析精油中的挥发性成分。结果共鉴定出47种挥发性成分,其中包括含硫化合物28种、醛类4种、醇类3种、酮类3种、烃类化合物9种。含硫化合物数量多且含量大,是新鲜野韭菜花中的主要挥发性成分。
