摘要
介绍了一种可准确、快速测定粮食、食品、饲料中玉米赤霉烯酮含量的液相色谱方法。比较了液液萃取、多功能净化柱、硅胶柱和免疫亲和柱的净化效果,筛选出最佳的提取、净化方案。最佳方案的检出限为3.9μg/kg,液液萃取净化法的回收率在92.1%～101.9%之间,多功能净化柱净化法的回收率在86.5%～95.8%之间。
A liquid chromatographic method of sensitive, rapid, reproducible, and reliable is described for determination of zearalenone in grain. Compare the different purification by partition, affintity column, muhifunctional column and silica gel. The limit of detection was 3.9μg/kg;recovery ranged 92. 1%-101.9%by partition and 86.5%-95. 8 % by muhifunctional column.
