同时蒸馏萃取-气相色谱-质谱联用分析长裙竹荪挥发性成分

Simultaneous Distillation Extraction and GC-MS Analysis of Volatile Components in Dictyophora indusiata Fisch

以二氯甲烷为溶剂,采用同时蒸馏萃取法,结合气相色谱-质谱联用技术对长裙竹荪挥发性成分进行分析。通过中等极性柱和弱极性柱双柱定性分析,共鉴定出70种化合物,包括醇类5种、酚类4种、醛类10种、杂环类17种、酮类13种、烃类12种、酸类5种、酯类4种,其中含量较高的化合物有呋喃甲醛、苯乙醛、2-乙酰基呋喃、β-绿叶烯、亚油酸、异长叶烯酮等。

The volatile components in Dictyophora indusiata Fisch ＇were extracted by simultaneous distillation and extraction （SDE） with dichloromethane as extraction solvent and analyzed by gas chromatography-mass spectrometry （GC-MS）. A total of 70 compounds were identified using mid-polar and weak-polar columns, including 10 aldehydes, 13 ketones, 5 alcohols, 4 hydroxybenzenes, 4 esters, 5 acids, 12 hydrocarbons, and 17 heterocyclic compounds. Predominant among them were benzeneacetaldehyde, furfural, 1-（2-furanyl）-ethanone, ~r -patchoulene, （Z,Z）- linoleic acid, isolongifolen-5-one, etc.
