Method for rapidly detecting albendazole and metabolite residue of albendazole in poultry eggs

The invention relates to the field of detection of albendazole and metabolite thereof, in particular to a method for rapidly detecting the residual quantity of albendazole and metabolite thereof in poultry eggs, which is a high performance liquid chromatography and high resolution mass spectrometry combined method, and comprises the following steps: sequentially adding an acetonitrile solution, anhydrous sodium sulfate and n-hexane into a poultry egg sample; and performing nitrogen blowing, and dissolving residues in a constant volume by using a methanol aqueous solution to obtain a sample solution suitable for analysis of a high performance liquid chromatography and high resolution mass spectrometry combined detector. Therefore, accurate, reliable and rapid content detection of albendazole and metabolites thereof is realized by using a high-resolution mass spectrometer. According to the method disclosed by the invention, complicated steps such as a solid-phase extraction column and the like are not needed, t
