Simultaneous Determination of 30 Foodborne Stimulant Drug Residues in Animal-Derived Foods by Ultra-high Performance Liquid Chromatography-Tandem Mass Spectrometry with Pass-Through Solid Phase Extraction

Abstract

In order to solve the problems of the detection of various foodborne stimulants in different animal-derived foods such as significant differences in matrix effects and many types of interference, a method was established for the determination of 10 protein anabolic agents, 8 glucocorticoids, and 12 diuretics in animal-derived foods by pass-through solid phase extraction (SPE) and ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with 5% formic acid in acetonitrile, and the extract was purified by pass-through solid phase extraction before being analyzed by UPLC-MS/MS. The internal standard method was used for quantification. The results showed that good linearity was observed for all analytes within their respective concentration ranges. The average recoveries ranged from 67.5% to 114.3% with relative standard deviations (RSDs) between 0.7% and 16.1% (n = 6). This method is characterized by high sensitivity, simple operation, high throughput and high detection efficiency, which improves the measurement accuracy of different complex matrices and can meet the need for the detection of the 30 foodborne stimulants in animal-derived foods used in sports events.
