芹菜籽香气成分研究

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％）．

Study on Aromatic Components of Celery Seeds

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 %).
