A simple and inexpensive method was developed using solid-phase extraction, together with high performance liquid chromatographic method with UV detection for determination of Cyantraniliprole and its metabolite (J9Z38) residues. The evaluated parameters include the extracts by silica gel packed column using acetonitrile and water solvents. The method was validated using fruit samples spiked with Cyantraniliprole and its metabolite (J9Z38) at different fortification levels (0.01 and 0.1 μg/g). Average recoveries (using each concentration six replicates) ranged 83–94%, with relative standard deviations less than 2%, calibration solutions concentration in the range 0.01–10.0 μg/mL and limit of detection (LOD) and limit of quantification (LOQ) were 0.003μg/g and 0.01μg/g respectively. Finally the fruit residue samples were analyzed by HPLC.
