Abstract:  Head space solid phase microextraction (SPME) technique was employed to extract volatile compounds of essential oil from weizhou honeyorange. Volatile compounds of essential oil were isolated and identified successfully by capillary gas chromatography-mass spectrometry (GC-MS),and 42 components were identified. It was found the main components were Isolimonen (25.92%),2-(1-Methylethylidene)-bicyclo2,2heptane (19.82%),4-Methyl-1-(1-methylethenyl)-cyclohexene (15.81%),2-Ethyl-1-octen-3-yne(9.20%),β-myrcene (8.59%),(E)-3,7-Dimethyl-1,3,6-octatriene (6.41%). The volatile components identified is 98.77% in volatile compounds.

Key words: honeyorange essential oil, head space solid phase microextraction(HS-SPME), gas chromatography-mass spectrometry(GC-MS), volatile compounds
