摘　　要：采用顶空固相微萃取法萃取荜茇果穗挥发性成分,并用GC-MS进行分析.3种萃取纤维头共萃取出49个成分,鉴定出42个成分.使用DVB/CAR/PDMS萃取纤维头时共检测出36种成分,解析鉴定出占总成分99.834%的35种成分,主要成分为β-石竹烯(17.933%)、β-毕澄茄油烯(15.892%)、十五烷(8.285%)、β-芹子烯(6.673%)和β-反式罗勒烯(6.166%)等;使用CW/DVB萃取纤维头时共检出40种成分,解析鉴定出占总成分99.622%的36种成分,主要成分为β-毕澄茄油烯(26.241%)、β-石竹烯(19.650%)、十五烷(8.523%)、β-芹子烯(6.572%)和十三烷(5.037%)等;使用CAR/PPMS萃取纤维头时检出38种成分,解析出占总成分99.515%的35种成分,主要成分为β-石竹烯(17.858%)、β-毕澄茄油烯(17.804%)、十五烷(8.409%)、β-芹子烯(6.485%)和十三烷(5.940%)等.Three kinds of HS-SPME fiber were used to extract the volatile compositions of long pepper in this paper, which were analyzed by GC-MS. Fourty-nine constituents were extracted by the three kinds of fiber in total, and 42 compounds were identified. Thirty-six compounds were separated by using DVB/ CAR/PDMS fiber, and 35 constituents （ 99. 834% of the total） were identified. The major compositions were β-Caryophyllene （17. 933% ） , β-Cubebene （15. 892% ） , Pentadecane （8. 285% ） , β-Eudesmene （6. 673% ） and β-trans-Ocimene （6. 166% ）. Fourty compounds were separated by using CW/DVB fi- ber, and 36 constituents （99. 622% of the total） were identified. The major compositions were β-Cube- bene （26. 241% ）, β-Caryophyllene （19. 650% ）, Pentadecane （8. 523% ）, β-Eudesmene （6. 572% ） and Tridecane （5. 037% ）. Thiry-eight compounds were separated by using CAR/PDMS fiber, and 35 constituents （99. 515% of the total） were identified. The major compositions were β-Caryophyllene （17. 858% ）, β-Cubebene （ 17. 804% ）, Pentadecane （ 8. 409% ）, β-Eudesmene （6. 485% ） and Tridecane （5. 940% ）.
