Abstract:

A method was established for the determination of 50 kinds of antibiotic residues (macrolides, quinolones, sulfonamides, tetracyclines, nitroimidazoles, lincomycin and chloramphenicol) in drone pupa powder by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The samples were extracted with perchloric acid and lead acetate solution, and the protein was precipitated. The extraction solution was adjusted to pH 8 using dipotassium hydrogen phosphate, then the solution was purified by solid phase extraction (SPE) and analyzed by LC-MS/MS. The target compounds in the drone pupa powder were determined quantitatively and quantitatively by using multiple reaction monitoring and positive ion or negative ion modes. The recoveries of the 50 antibiotics were in the range of 70.2%-118.3%, and the relative standard deviations (RSDs) were 1.8%-13.6%. The method is simple, selective, and can be suitable for the analysis and confirmation of veterinary drug residues in drone pupa powder.

Key words: antibiotic residues, drone pupa powder, liquid chromatography-tandem mass spectrometry (LC-MS/MS), solid phase extraction (SPE)
