中文摘要: 采用5种不同涂层纤维的萃取头对细叶韭花水提液中易挥发性成分进行萃取，结合顶空固相微萃取（headspace solid phase microextraction，HS-SPME）-气相色谱－质谱法（gas chromatography-mass spectrometry，GC-MS）对细叶韭花水提液中的易挥发成分进行分析鉴定。结果表明，细叶韭花水提液的易挥发性成分共检测出97种化合物，其中含硫化合物7种，酯类化合物15种，酸类化合物8种，碳氢化合物31种，醇类化合物12种，酮类化合物7种，醛类化合物10种，酚类化合物3种，醚类和其它类化合物各2种。相对含量较高化合物主要是含硫化合物、酯类、酚类、酸类物质，且5种萃取头得到的10种共有成分中对细叶韭花水提液风味成分贡献最大的是二甲基三硫醚、二甲基四硫醚和大马士酮。
Abstract:The volatile components from Allium tenuissimum flowers water extracts were analyzed and identified by gas chromatography-mass spectrometry（GC-MS）using five extraction heads with different coated fiber combined with head space solid phase micro-extraction（HS-SPME）.The results showed that a total of 97 components were confirmed in water extract，in which included 7 sulfurs，15 esters，8 acids，31 hydrocarbons，12 alcohols，7 ketones，10 aldehydes，3 phenols，2 ethers and 2 other compounds.The main compounds with higher relative content were sulfur compounds，esters，phenols and acids，and the common compounds coming from the five kinds of extraction heads studied with most significant contribution to the flavor components of the water extract of Allium tenuissimum flowers a was found to be dimethyl trisulfide，dimethyl tetrasulphide and β-damascenone.
