摘要: 本研究旨在建立以免疫亲和色谱(IAC)柱为净化手段的高效液相色谱荧光检测方法(HPLC-FLD),可同时检测牛肌肉组织中的阿维菌素、伊维菌素、多拉菌素和埃普里诺菌素残留。样品用甲醇提取,IAC柱净化,以乙酸酐—甲基咪唑的乙腈溶液作衍生化试剂,96 ℃条件下,完全衍生化100 min。在5、10、50和100 ng/g添加水平下,牛肌肉组织中4种药物添加回收率为77.3%~119.5%,变异系数为1.5%~18.9%,方法的检测限为0.8 ng/g。该方法可用于检测牛肌肉组织中的阿维菌素类药物残留。

Abstract: A HPLC method was developed with immunoaffinity chromatography columns(IAC)as purify process to detect the residual of avermectin,ivermectin,doramectin and eprinomectin in bovine muscle tissue.Samples were extracted with methanol,purified by IAC and followed by derivatization with acetic anhydride and 1-methylimidazole in acetonitrile.The optimum time required for the completion of derivation reaction of the 4 drugs was 100 min at 96 ℃.Recoveries ranged from 77.3 % to 119.5% with CV from 1.5% to 18.9% when these drugs were spiked in bovine muscle at levels of 5,10,50 and 100 ng/g.The limit of detection of the method was 0.8 ng/g in bovine muscle tissue.This method could be used to detect the residual of avermectins in bovine muscle tissue.
