| 摘要 | [Objectives] This study was conducted to establish a method for determining residual coumoxystrobin in vegetables using QeEChERS-liquid chromatography-tandem mass spectrometry (QeEChERS-LC-MS/MS). [Methods] The sample was extracted by acetonitrile, and the extract was purified by QeEChERS, concentrated by nitrogen blowing, and then detected. [Results] Coumoxystrobin had a good linear relation in the range of 0.01-10.0 mg/kg, and the linear equation was y=4 686.92 * x+5 683.28, R2=0.999. The limit of detection was 0.001 mg/kg, and the limit of quantitation was 0.003 mg/kg. [Conclusions] The method has the advantages of convenient and fast operation and stable detection process, and can provide technical support for the supervision and monitoring of coumoxystrobin. |
