Abstract
A rapid, effective and sensitive method to quantitatively determine ametoctradin residue in apple, cucumber, cabbage, tomato and grape was developed and validated using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS). The target compound was determined in less than 5.0 min using an electrospray ionisation source in positive mode (ESI+). The limit of detection was below 0.043 μg kgâ1, whereas the limits of quantification did not exceed 0.135 μg kgâ1 in all five matrices. The method showed excellent linearity (R2 > 0.9969) for the target compound. Recovery studies were performed in all matrices at three spiked levels (1, 10 and 100 μg Lâ1). The mean recoveries from five matrices ranged from 81.81% to 100.1%, with intra-day relative standard deviations (RSDr) in the range of 0.65-7.88% for the test compound. This method will be useful for the quick and routine detection of ametoctradin residues in potato, grape, cucumber, apple and tomato.
