Analytes were extracted using the dispersive liquid-liquid microextraction technique and determined by GC-ECD. Parameters affecting the dispersive liquid-liquid microextraction performance, such as the kind and volume of extraction and dispersive solvents, extraction time and salt concentration, were studied and optimized. Under the optimum extraction conditions, the linearities of the method were obtained in the range of 0.5-20.0μgkg−1 for triadimefon, hexaconazole, diniconazole and procymidone, and 1.0-40.0μgkg−1 for myclobutanil and iprodione, with the correlation coefficients ranging from 0.9902 to 0.9995. The enrichment factors ranged from 685 to 820 and the extraction recoveries ranged from 81.3 to 98.4%. The relative standard deviations varied from 3.1 to 7.8%. The limits of detection of the method were in the range of 0.02-0.12μgkg−1. Results showed that the method we proposed can meet the requirements for the determination of target fungicides in fruit samples. Several compounds considered in this study were found in fruit samples.
