采用顶空固相微萃取法结合气相色谱-质谱联用对汉麻叶的挥发性成分进行分析,考察3种不同萃取纤维（DVB/CAR/PDMS,CAR/PDMS,PDMS/DVB）对分析结果的影响,结果表明较佳萃取纤维为CAR/PDMS.从汉麻叶中检出59种挥发性成分,占挥发油总组分的93.18%,其中醛类3种（0.71%）、醇类1种（0.06%）、烃类37种（57.23%）、杂环化合物类3种（0.19%）、萜烯类12种（34.49%）、其他3种（0.50%）.在鉴定出的成分中含量较多的是[1R-（1R＊,4Z,9S＊）]-4,11,11-三甲基-8-亚甲基-二环[7.2.0]4-十一烯（18.81%）、（1α,3α,5α）-1,5-二甲基-3-甲基-2-亚甲基环己烷（18.18%）、α-石竹烯（11.52%）、异柠檬烯（6.78%）等.

The volatile components of China-Hemp leaves were extracted by headspace solid-phase micro- extraction (HS-SPME) apparatus with three different fibers (divinylbenzene/earboxen/polydimethylsilox- ane DVB/CAR/PDMS, carboxen/polydimetylsiloxane CAR/PDMS, polydimetylsiloxane/divinylbenzene PDMS/DVB). The results showed that the fiber of CAR/PDMS had the best extraction efficiency. A total of 59 compounds were analyzed and identified by gas chromatography-mass spectrometry(GC-MS). The volatile components were accounted for 93. 18% in total, including 3 aldehydes(0. 71% ), 1 alcohol (0.06%), 37 hydrocarbons(57.23% ) 3 heterocyclie compounds(0. 19% ), 12 terpenoids(34.49% ) and 8 other compounds (25.64%). The prominent compounds were [ 1 R-( 1R * ,4Z ,9S * )] 4,11,11- Trimethyl-8-methylene-bieyclo [ 7.2.0 ] undee-4-ene ( 18.81% ), ( 1 a, 3 a, 5 a ) -1,5 -Diethenyl-3 -methyl- 2-methylene-cyclohexane ( 18. 18 % ), a-Caryophyllene ( 11.52 % ), ( 3 R-trans ) -3-Methyl-6- ( 1 -methyle- thenyl) -cyclohexene ( 6.78 % ) etc.
