摘要: 建立了鸡组织中环丙沙星、诺氟沙星、恩诺沙星的高效液相色谱(HPLC)测定方法,并测定了鸡单次内服(10mg/kg·d)单种药物和混合药物后组织中的药物残留特征。组织样品用磷酸盐缓冲液提取,用100mgC18固相萃取柱净化,收集洗脱液作HPLC检测。色谱柱为HypersilBDS-C18柱;荧光检测器,激发波长278nm,发射波长445nm;流动相为磷酸/三乙胺(pH2.5)-乙腈(86:14)溶液,pH值为2.5。环丙沙星、诺氟沙星、恩诺沙星三种药物标准溶液的最低检测限分别为20、25和25ng/ml(g);血浆样品回收率大于82%,组织样品回收率大于72%。

Abstract: A high-performance liquid chromatographic method was reported for the quantitative determination of residues of three fluoroquinolones in broiler chicken tissues after a single oral administration (10mg/kg·d) were studied in this paper. The residua was extracted with phosphate buffer solution (PBS) and cleaned up by solid-phase extraction column C18 and determinnated by high perfomance liquid chromatography (HPLC) analysis. The samples were analyzed by a fluorescence detector (FLD) at excitation wavelength 278nm and emission wanelength 445nm. The minimal detection limits for the determination (μg/g) are 0.020 for ciprofloxacin, 0.025 for norfloxacin, and 0.025 for enrofloxacin.
