采用3种萃取纤维头的顶空固相微萃取法萃取荜茇果穗挥发性成分

摘要：采用项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．

Extraction of Volatile Compositions From Long Pepper by HS-SPME With Three Kinds of Fiber

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% ）.
