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 fiber, and 36 constituents (99.622% of the total) were identified. The major compositions were β-Cubebene (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%).
