Abstract:

An ultra high performance liquid chromatography-tandem mass spectrometric method was established for the determination of 38 forbidden anti-infective drugs in 2 matrixes of cosmetics. The cosmetic samples were extracted with solvent and performed on a Waters BEH C18 (2.1 mm×100 mm, 1.7 μm) column with binary mobile phase consisting of 0.1% ammonium acetate pH=4.0 (solvent A) and 0.1% formic acid methanol solution (B) with gradient elution. Samples were analyzed by electronic spray ionization under a positive ion or negative ion mode with multiple reaction monitoring (MRM), and then quantified by an external standard curve. The calibration curve of chloramphenicol is linear within the range of 100-1 000 μg/L and the calibration curves of the other 37 target compounds are linear within the range of 15-150 μg/L with the correlation coefficients above 0.99. The limits of detection (LOD) and limits of quantitation (LOQ) are in the ranges of 0.3-240.4 μg/kg and 1.1-801.2 μg/kg, respectively. The recoveries for 38 prohibited anti-infective drugs at three spiked levels are in the range of 79.0%-119.8% with the relative standard deviations (RSD) of 0.3%-9.7%(n=6). The method is simple, rapid and accurate, and quite suitable for the simultaneous determination of illegally added anti-infective drugs in aqueous and cream cosmetics.
