要旨

A rapid and sensitive ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method was developed for the determination of cyadox (CYX) and its three major metabolites, quinoxaline-2-carboxylic acid (QCA), 1-desoxycyadox (1-DCYX) and 1,4-bisdesoxycyadox (BDCYX) in fish. Samples were extracted with acetonitrile–0.5 M hydrochloric acid (9 + 1) and cleaned up using Oasis MAX cartridges. The total time taken for separation by UPLC was less than 5 min. The four target compounds were then determined by ESI-MS/MS. At the fortified levels of 2–50 μg kg−1 in fish, recoveries of all the compounds ranged from 80.2% to 88.2%, with a relative standard deviation of 6.8 to 14.6%. Limits of detection for CYX, QCA, 1–DCYX and BDCYX were 0.52, 1.07, 0.69 and 0.38 μg kg−1, respectively.

Analytical Methods welcomes early applications of new analytical and bioanalytical methods and technology demonstrating the potential for societal impact. We require that methods and technology reported in the journal are sufficiently innovative, robust, accurate, and compared to other available methods for the intended application. Developments with interdisciplinary approaches are particularly welcome. Systems should be proven with suitably complex and analytically challenging samples. We encourage developments within, but not limited to, the following technologies and applications: global health, point-of-care and molecular diagnostics biosensors and bioengineering drug development and pharmaceutical analysis applied microfluidics and nanotechnology omics studies, such as proteomics, metabolomics or glycomics environmental, agricultural and food science neuroscience biochemical and clinical analysis forensic analysis industrial process and method development
