| Abstract | Cyantraniliprole is one of the novel anthranilic diamide insecticides designed to target the insect ryanodine receptor and has been used widely in many vegetables and fruits, especially melon. A highly selective and sensitive determination method is required to ensure that only permitted levels of cyantraniliprole are consumed. In this work, the combination of quick, easy, cheap, effective, rugged, and safe (QuEChERS) with high-performance liquid chromatography-ultraviolet (HPLC-UV) is proposed for the determination of cyantraniliprole in melon. Insecticide was spiked into melon samples before analysis, extracted by using QuEChERS, and determined by HPLC-UV. The important parameters that affect the QuEChERS efficiency were investigated. NaCl was the best partitioning salt with the highest recovery (129.8%-140.9%, relative standard deciation (RSD) 4.5%) while Florisil (60-100 mesh) was the sorbent, which provided chromatograms with less interference. The mean recoveries were within 129.2%-111.7% (RSD 7.1%). Under the optimized conditions, the proposed extraction method provided higher sensitivity compared with the traditional solvent extraction method. The limit of detection and the limit of quantification for cyantraniliprole were determined to be 0.14 and 0.46 mg/kg, respectively. Moreover, the matrix effect was evaluated, and the matrix-matched calibration method was applied. The cyantraniliprole residues on melon grown in the experimental field were mainly found in leaves, and no residues were detected in fruit on the harvest day. The half-life of cyantraniliprole on melon leaves was determined as 4.4 days. This study could guide the anticipated use of cyantraniliprole for melon. |
