A sensitive and specific high performance liquid chromatographic technique is described for the determination of ivermectin in milk. Milk samples (1 ml) were extracted with organic solvent (iso-octane and acetonitrile) and then chromatographed using reversed phase system. Specificity of the assay was confirmed by the use of mass spectrometry. After an subcutaneous administration of ivermectin (0.2 mg/kg) in a cow, ivermectin was detected in milk for about three weeks and over this period milk and plasma concentration were of the same order of magnitude.
描述了一种灵敏且特异的高效液相色谱技术,用于测定牛奶中的伊维菌素。取1毫升牛奶样品,用有机溶剂(异辛烷和乙腈)萃取,然后采用反相系统进行色谱分析。通过质谱法确认了该分析方法的特异性。给一头奶牛皮下注射伊维菌素(0.2毫克/千克)后,在牛奶中检测到伊维菌素约三周,在此期间牛奶和血浆中的浓度处于相同数量级。
