Abstract:
Objective:To develop a method for Simultaneous and rapid determination of 12 rodenticides including pindone, vacor, coumatetralyl, warfarin, diphacinone, coumachlor, chlorphacinon, difenacoum, brodifacoum, bromadiolone, difethialone and flocoumafen in whole blood and urine samples by high performance liquid chromatography-tandem mass (LC-MS-MS) .
Methods:The whole blood samples were precipitated with acetonitrile, purified by OstroTM 96-well plate, The urine samples were extracted by acetonitrile, and then separated on a ODS column, analyzed with high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) . The external standard calibration were tested.
Results:A good linearity was observed in their respective concentration ranges of 12 rodenticides. The related coefficients were 0.993 0~0.999 8. The limit of detections were 0.05 μg/L~1.4 μg/L. The rates of recovery were 92.5%~118.0%. The relative standard deviations were between 0.8%~17.3%.
Conclusion:The method was simple, rapid, sensitive, accurate and suitable for simultaneous detection of the 12 rodenticides in whole blood and urine samples of intoxicated patients.
