title: Approach for Pesticide Residue Analysis for Metabolite Prothioconazole-desthio in Animal Origin Food.
abstract: Food safety problems such as damage to immune, nervous, and endocrine systems leading to cancer and malformations have received increasing attention. To achieve the maximum residue limits, the most discussed method of high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) is widely used with a advantage of high precision and resolution. Prothioconazole is a broad-spectrum thiocarbamate fungicide. It can rapidly metabolize to prothioconazole-desthio in different matrixes. Rapid and effective methods for the determination of prothioconazole-desthio in five kinds of different animal food were developed. Samples were extracted with acetonitrile or acetonitrile/water and determined by HPLC-MS/MS. The limit of detection and limit of quantification values of prothioconazole-desthio were 0.015 and 0.05 mg/kg for porcine liver and kidney, 0.0015 and 0.005 mg/kg for pork, and 0.003 and 0.01 mg/kg for eggs, together with 0.0012 and 0.004 mg/kg for milk of the detected method, respectively. A good linear regression trend can be observed in a certain concentration range for all of the animal food. At fortified levels, recoveries were between 83.6 and 105%, with relative standard deviations of 1.5-10.3%. A sample survey of 150 samples with 30 samples for each kind of animal food across the country was conducted and found that there was no prothioconazole-desthio detected in all samples.
