| 摘 要： | 本文研究建立了甘蓝和橙子中阿维菌素农药残留的超高效液相色谱紫外(UPLC-UV)检测方法。样品经乙腈提取,混合使用乙二胺-N-丙基硅烷(PSA)和C_(18)基质分散净化剂进行净化,采用ACQUITY UPLC BEH C_(18)色谱柱(2.1×100 mm,1.7μm),以乙腈:水(V/V=70:30)为流动相,流速0.25 m L/min,柱温:35℃,紫外检测波长:245 nm。阿维菌素在甘蓝和橙子样品中存在程度不同的基质效应,故采用空白基质匹配的校准曲线外标法定量。结果表明,阿维菌素在0.25~10 mg/L范围内具有良好的线性关系,相关系数均大于0.9999。在0.05~0.5 mg/kg范围内,平均添加回收率为83.0%~100.2%,相对标准偏差为1.17%~1.30%。阿维菌素在甘蓝和橙子中的检出限(LOD)分别为0.0109和0.0160 mg/kg。该方法操作简单、准确、灵敏,可用于甘蓝和橙子中阿维菌素的分析。
