摘  要:采用同时蒸馏萃取(SDE)提取资中冬尖中的挥发性香味物质,利用气相色谱-质谱联用仪(GC-MS)对其挥发性香味成分进行分离和鉴定确认了23种成分。初腌冬尖中含量最高的是甲醇(0.061%)、2-丁烯(0.044%)、反1,2-二氯乙烯(0.032%)和二甲基硫(0.029%);腌制一年的冬尖中含量最高的是亚麻酸乙酯(0.056%)、甲醇(0.056%)、2-丁烯(0.039%)和反1,2-二氯乙烯(0.033%);两年冬尖中含量最高的是亚麻酸乙酯(0.138%)、2-丁烯(0.039%)、反1,2-二氯乙烯(0.031%)和乙酸(0.030%);特制冬尖中最高含量是二甲基硫(0.09%)、过氯乙烯(0.08%)、十八烷三烯酸乙酯(0.072%)和反1,2-二氯乙烯(0.069%)。The volatile compounds in Zizhong Dongjian with simultaneous distillation and extraction (SDE) are analyzed by gas chromatograph-mass spectrometry (GC-MS). Twenty-three volatile com- pounds are effectively obtained with SDE in Dongjian by GC-MS. The main constituents are Methyl alcohol (0. 061%), 2-Butene (0. 044%), Ethene, 1, 2-dichloro (0. 032%), Dimethylsulfide (0.029%) in preliminary picked Dongjian. The Ethyl linolenate (0.056%), Methyl alcohol (0.056%), 2-Butene (0.039%), Ethene, 1, 2-dichloro (0. 033%) were the major compounds in one year pickling Dongjian. The Ethyl linolenate (0. 138%), 2-Butene (0. 039%), Ethene, 1, 2-dichloro (0.031%), Acetic acid (0.030%) are the major sulfide (0.09%), chlorinated polyvinyl chloride ter (0. 072%), Ethene, 1,2-dichloro (0. 069%) compounds in two years pickled Dongjian. Dimethyl (0.08%), 9,12,15-Oct-adecatrienoic acid, ethyl es- are the major compounds in pickled Teiian.
