多功能净化柱-光化学衍生高效液相色谱法测定 成品植物油和花生原油中黄曲霉毒素B1Determination of aflatoxin B1 in finished vegetable oil and crude peanut oil by multifunctional clean-up column-photochemical derivatization and high performance liquid chromatography
为了快速、准确测定成品植物油和花生原油中黄曲霉毒素B1(AFB1)的含量,建立了采用多功能净化柱对油样进行前处理,再结合光化学衍生高效液相色谱法测定植物油中AFB1含量的方法,对前处理提取剂、高效液相色谱法的分析条件(色谱柱、进样量)进行优化,再通过与国标中免疫亲和柱法进行比较,对所建立的方法进行评价。结果表明:优化的条件为以乙腈-水溶液(84+16)为提取剂,采用Zorbax Eclipse XDB-C18色谱柱(4.6 mm×150 mm,5 μm),进样量10 μL;建立的方法加标回收率和精密度良好,定量限为0.2 μg/kg,低于GB 2761—2017规定的最低限量值要求,可满足企业...
