ABSTRACT
An ultra performance liquid chromatography-tandem mass spectrometric (UPLC-MS/MS) method was developed for the determination of 11 kinds of aminoglycosides (AGs), including paromomycin, spectinomycin, tobramycin, gentamycin, kanamycin, hygromycin B, apramycin, streptomycin, dihydrostreptomycin,amikacin and neomycin in aquatic products. Samples were extracted by phosphate buffer solution, and purified on molecularly imprinted polymers (MIP) solid phase extraction column. After separated by Obelisc R chromatographic column, AGs were detected by UPLC-MS/MS. It showed a good linearity relationship in the AGs concentration range of 1.0-1000 ng/mL with the correlation coefficient R2>0.994. The limit of detection (LOD,S/N≥3) was ranged from 1.0 μg/kg to 10.0 μg/kg,and the limit of quantitation (LOQ,S/N≥10) was ranged from 2.0 μg/kg to 20.0 μg/kg. Besides, the average recoveries presented 78.4%-109.6% with the relative standard deviation (RSD, n=6) of 2.3%-14.9%. This method was successfully applied to the simultaneous determination of 11 kinds of AGs with high sensitivity in aquatic products.
