Abstract:

A high performance liquid chromatography tandem mass spectrometry(HPLC-MS/MS) method was established for the determination of 15 quinolone antibiotics in cosmetics. The samples were extracted with 0.1% formic acid acetonitrile solution, degreased with n-hexane, separated by Thermo Hypersil GOLD C18(2.1 mm×100 mm, 1.9 μm) column, then detected by triple quadrupole mass spectrometry multi-reaction monitoring mode(MRM) to determine retention time and relative ion abundance, and quantified by external standard method. The results show that all of the 15 quinolone antibiotics show good linearity in the range of 5.0-200 μg/L with the correlation coefficients greater than 0.995 0. The limit of detection and quantification of the method are 0.15 and 0.50 mg/kg, respectively. The average recoveries of the spiked samples were ranged from 80.1% to 104.9% and the relative standard deviations(RSD, n=6) were in the range of 1.0%-7.4%. The method is accurate and reliable, which meets the requirements of the determination of quinolone antibiotics in cosmetics.

Key words: high performance liquid chromatography tandem mass spectrometry, cosmetics, antibiotics, quinolones
