摘要： This paper describes a rapid and sensitive method for the determination of eugenol in fish samples, based on solid-phase extraction (SPE) and gas chromatography-tandem mass spectrometry (GC-MS-MS). Samples were extracted with acetonitrile, and then cleanup was performed using C18 solid-phase extraction (SPE). The determination of eugenol was achieved using an electron-ionization source (EI) in multiple-reaction-monitoring (MRM) mode. Under optimized conditions, the average recoveries of eugenol were in the range 94.85-103.61 % and the relative standard deviation (RSD) was lower than 12.0 %. The limit of detection (LOD) was 2.5 mu g kg(-1) and the limit of quantification (LOQ) was 5.0 mu g kg(-1). This method was applied to an exposure study of eugenol residue in carp muscle tissues. The results revealed that eugenol was nearly totally eliminated within 96 h.
