摘 要:采用固相微萃取法萃取黑龙江产芹菜籽香气成分,然后用GC-MS进行成分分析,并与水蒸气蒸馏法获得的精油成分进行比较.用CAR on PDMS萃取柱进行顶空固相微萃取时,共检测出26种成分,鉴定出占总成份89.650%的20种成分,主要成分为柠檬烯(35.980%),β-月桂烯(20.500%),β-蛇床烯(16.160%),正戊基苯(5.295%),β-蒎烯(3.412%),α-蛇床烯(3.293%).水蒸汽蒸馏法提取芹菜籽,以1.18%产率获得精油,共检测出23个成分,鉴定出占总精油91.375%的18种成分,主要成分为柠檬烯(31.149%),β-蛇床烯(22.281%),对甲苯基异戊酸酯(14.944%),α-2-丙烯基苯甲醇(9.872%),β-月桂烯(4.324%)和α-蛇床烯(4.322%).Aromatic components of the celery seeds grown in Heilongjiang Province were analyzed by using solid phase microextraction combined with GC-MS and compared with the components of the essential oil. When using CAR on PDMS column, a total of 26 components were detected, in which 20 compounds that account for 89. 650 % of the total were identified. The main constituents were limonene (35.98 % ), β-myrcene (20.500 % ), β-selinene ( 16. 160 % ), n-pentylbenzene (5. 295 % ), β-pinene (3. 412 %) and α-selinene (3. 293 %). The essential oil was obtained by steam distillation extraction method in 1.18 % yield, A total of 23 constituents were detected, in which 18 compounds that account for 91. 375 % were identified. The main constituents were limonene (31. 149 %), β-selinene (22. 281% ), p-cresyl isovalerate ( 14. 944 % ), α-2-propenylbenzenemethanol (9. 872 % ), β- myrcene (4. 324 % ) and α-selinene (4. 322 % ).
