The invention discloses a method for detecting glucocorticoid in milk, which belongs to the technical field of analysis and detection. The method first uses polystyrene nanofibers to enrich glucocorticoids, and then uses ultra-high performance liquid chromatography-tandem mass spectrometry to detect 25 glucocorticoids in milk. In the invention, the polystyrene nanofiber extraction column can efficiently and quickly adsorb the glucocorticoid in the sample, so as to achieve the effects of removing interference, concentrating and enriching, and the method uses less organic solvent and reduces the analysis time. |
