Abstract:The volatile components of China-Hemp leaves were extracted by headspace solid-phase microextraction (HS-SPME) apparatus with three different fibers(divinylbenzene/carboxen/polydimethylsiloxane 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 heterocyclic compounds(0.19%), 12 terpenoids(34.49%) and 8 other compounds(25.64%). The prominent compounds were [1R-(1R*,4Z,9S*)]-4,11,11-Trimethyl-8-methylene-bicyclo[7.2.0]undec-4-ene(18.81%), (1α,3α,5α)-1,5-Diethenyl-3-methyl-2-methylene-cyclohexane(18.18%), α-Caryophyllene(11.52%), (3R-trans)-3-Methyl-6-(1-methylethenyl)-cyclohexene(6.78%) etc.
