In this study three analytical methods for the extraction of pesticide residues in spiked honey samples were evaluated. They have been applied to identification and quantification of targeted thirty five pesticides from different chemical groups and the possibility of identification of any other eluting compounds. Such methods are based on liquid-liquid extraction (LLE) with different organic sol-vents; ethyl acetate (method_1), n-hexane (meth-od_2) and (petroleum ether: ethyl acetate 80:20 v/v) (method_3), followed by clean-up with florisil and quantification by gas chromatography-electron-capture detection (GC-ECD). Recoveries of the applied spiked samples were ranged from (64.86 – 113.01 %), (64.67 – 111.28 %) and (67.48 – 107.82 %) with the three mentioned methods, respectively. The best results were obtained from ethyl acetate method.
