摘要： An ultra-performance liquid chromatography- tandem mass spectrometry(UPLC-MS/ MS) method has been developed for determination of 22 kinds of ss-agonists residues in swine, bovine and sheep muscle and liver samples. The animal food samples were extracted with enzymatic probe sonication(EPS) using ss-glucuronidase/sulfatase enzymes, followed by clean-up using automatic solid-phase extraction and determination by UPLC-MS/MS. The target analytes were quantified by internal standard methods. Under the optimized EPS conditions, one sample could be exhaustively extracted within 120 s( average recovery 81.2% -100.7%), as compared with 16 h needed for the conventional enzymatic digestion, which was more suitable for high-throughput screening. Furthermore, the clean-up was conducted using automatic solid-phase extraction, and 36 samples could be performed in 30 min simultaneously. The work efficiency was significantly improved, and the relative standard deviations(RSDs) were relatively low(0.3%- 7.9%). As compared with the traditional enzymatic digestion and solid- phase extraction techniques, the newly developed method was quick and easy to be performed, which was more suitable for high- throughput detection in routine residual analysis.
