A liquid chromatographic (LC) method is described for determination of olaquindox residues in swine tissues. The drug is extracted from tissues with acetonitrile, and the extract is evaporated to dryness. This residue is cleaned up by alumina column chromatography. LC analysis is carried out on a Nucleosil C18 column, and olaquindox is quantitated by ultraviolet detection at 350 nm. The average recoveries of olaquindox added to tissues at levels of 0.2, 0.1, and 0.05 ppm were 74.0, 68.6, and 66.3%, respectively. The detection limit was 2 ng for olaquindox standard and 0.02 ppm in tissues.
本文描述了一种用于测定猪组织中喹乙醇残留量的液相色谱（LC）方法。用乙腈从组织中提取该药物，提取物蒸发至干。此残留物通过氧化铝柱色谱法进行净化。在Nucleosil C18柱上进行LC分析，喹乙醇通过在350nm处的紫外检测进行定量。添加到组织中浓度为0.2、0.1和0.05ppm的喹乙醇的平均回收率分别为74.0%、68.6%和66.3%。喹乙醇标准品的检测限为2ng，组织中的检测限为0.02ppm。
