摘　　要：采用顶空固相微萃取-气相色谱-质谱法萃取和分析孜然粉末香气,共检测出19种成分,解析鉴定出占总挥发性成分99.695%的18种成分,主成分是两种蒈烯醛异构体(33.174%)、γ-松油烯(17.858%)、枯茗醛(17.280%)、β-蒎烯(13.940%)和对伞花烃(6.541%)。以水蒸汽蒸馏法提取孜然,精油的得率为2.6%,用GC-MS联机对精油进行了成分分析,检测出28个成分,解析鉴定了占精油99.801%的26个成分。主要成分为枯茗醛(39.511%)和两种蒈烯醛异构体(35.249%),其次为γ-松油烯(7.096%)、α-7-松油烯醇(5.315%)、β-蒎烯(5.242%)和对伞花烃(3.000%)。Volatile components of cumin powder were extracted and analyzed by head space solid and gas chromatography-mass spectrometry. 19 Components were detected and 18 compounds （99. 695% of total） were identified. 2 Kinds of carenal （33. 174%） were the main compounds, followed γ-terpinene （17. 858%）, cuminal（17.280%）,β-pinene （13.940%） and p-cymene （6.541%）. The yield of essential oil by steam distillation is 2.6%. 28 Components were detected and 26 components （99. 801% of the total essential oil） were identified by GC MS. Cuminal （39.511%） was the main compound, followed 2 kinds of carenal （35.249%）,γ-terpinene （7.096%）.α-terpinen-7-ol（5.315%）,β-pinene （5.242%） and p-cymene（3.000%）.
