Abstract:

In order to establish an general, efficient and accurate residue analysis method for high risk quinolone antibiotics in cultured aquatic products, such as Larimichthys crocea, Carassius auratus, Pelodiscus sinensis, etc, all the samples were extracted using ultrasonic and vibrating extraction coupling, and then cleaned by liquid-liquid extraction and determined by UPLC-MS/MS. The optimal pretreatment conditions were determined by combining hydrochloric acid concentration in extraction reagent, oscillation time, ultrasonic time, nitrogen blowing pressure, temperature with Box-Behnken response surface analysis. The matrix effects of the target objects were evaluated in this study, and the compensation method of matrix effects in Larimichthys crocea, Carassius auratus, Pelodiscus sinensis, Penaeus vannemei, Scylla serrata and its gonad, and Sinonovacula constricta was discussed by isotope internal standard and matrix matching curve. The results showed that the average recovery rate of 6 target substances was 82.20%-118.00%. The linear correlation coefficients were above 0.997 in spiked range of 0.2-20 ng·mL-1. The limits of detection and limits of quantitation were 0.5 μg·kg-1 and 1.0 μg·kg-1, respectively. It showed that the method met the requirements for the analysis of antibiotic residues in cultured aquatic products. To varying degrees, the matrix of Penaeus vannamei, Scylla serrata gonad and Larimichthys crocea inhibited the 6 target substances. The matrix matching curve and internal standard method could compensate the matrix effect effectively.
