Abstract: A simple and inexpensive method was developed using liquid - liquid extraction, together with high performance chromatographic method for determination of ametoctradin residues in grapes. The evaluated parameters include the extracts by distilled water and acetonitrile solvents. The method was validated using grapes samples spiked with ametoctradin at different fortification levels (0.05, 0.1 and 0.5 µg/g). Average recoveries (using each concentration three replicates) ranged 87-96%, with relative standard deviations less than 5%, calibration solutions concentration in the range 0.05-5.0 µg/mL and limit of detection (LOD) and limit of quantification (LOQ) were 0.02µg/g and 0.05µg/g respectively. Finally the grapes residue samples were analyzed by HPLC.
