Abstract:

The aim was to establish a rapid method for the determination of antibiotics and nitroimidazoles in skin care hyaluronic acid by high performance liquid chromatography tandem mass spectrometry. Ten reagents for each of the two kinds of antibiotics were selected. After vortex oscillation, ultrasonic extraction, centrifugation and filtration, the mixed solution samples of the two kinds of antibiotics were prepared. They were separated by chromatographic column, ionized by electrospray ionization in positive ion mode and detected by multiple reaction monitoring mode under gradient elution. The results show that the total ions of 10 compounds contained in the solution samples of the two antibiotics have separation reactions at different times and produce corresponding response values, showing a good linear correlation. The correlation coefficient results are 0.997 and above 0.996, respectively. The detection limits and quantitative limits of the two antibiotics are 1.6, 6 mg/kg, 0.9-201 mg/kg and 5-401 mg/kg, respectively. The method can accurately and efficiently complete the rapid determination of antibiotics and nitroimidazoles in skin care hyaluronic acid.

Key words: high performance liquid chromatography-tandem mass spectrometry, rapid determination, skin care hyaluronic acid, antibacterial drugs
