A method was developed for qualitative detection of ivermectin residues. It involves extraction of 1 g tissue sample with 5 mL acetonitrile and C18 solid-phase extraction. After derivatization with trifluoroacetic anhydride, the extract is purified again on the same but previously reconditioned C18 column. The eluate is evaporated, and the residue is diluted in methanol. The method allows detection of residues in swine and cattle meat, liver, and fat at levels as low as 5 micrograms/kg.
开发了一种定性检测伊维菌素残留的方法。该方法包括用5毫升乙腈提取1克组织样品并进行C18固相萃取。用三氟乙酸酐衍生化后，提取物在同一根但先前已重新处理过的C18柱上再次纯化。洗脱液蒸发后，残留物用甲醇稀释。该方法能够检测猪和牛的肉、肝脏及脂肪中低至5微克/千克水平的残留。
