摘要
Residues of 14 kinds of beta-lactam and macrolide antibiotics in bovine muscles were extracted with acetonitrile and the extract was partitioned with n-hexane, to remove fat. High-performance liquid chromatography was carried out on a TSK-gel ODS-80TM column using gradient elution with acetonitrile-0.05% trifluoroacetic acid and the drugs were quantitated by diode array detection. The recoveries of the drugs from bovine muscles spiked at 0.1 ppm were over 63% and each quantitation limit was 0.04 ppm.
