A method for determination of flumethrin residues in honey by using HPLC (high performance liq-uid chromatography) has been developed and validated. The sample was extracted from honey by the mix extractions of n-hexane and dichloromethane (4:6,V/V), concentrated by rotary evaporator, purified by HLB SPE cartridge, and detected at a wavelength of 267 nm. The pre-treatment conditions were optimized in order to decrease the matrix interference. The detection limit for flumethrin was 0.005 mg·kg-1. The average recoveries for flumethrin were be-tween 80.8%and 96.8%. Coefficients of variation ranged from 0.6%to 1.5%. The method has good repeatability and high sensitivity, and can be applied for the determination of flumethrin residues in the honey.
