摘要
建立检测谷物中脱氧雪腐镰刀菌烯醇(DON)的液相色谱方法,通过不同提取方法的比对来确定最佳的DON提取方案,并最终确定使用乙腈-水(体积比V/V,84/16)提取,经过DON专用净化柱的净化处理后,采用紫外检测器(λ=220nm)CLC18亲水分离柱测定。结果表明,用高速均质机均质4min提取,可大幅度提高方法回收率,回收率达到90.7%-98.9%,方法最低检出限为50μg/kg。
A HPLC method was developed for deoxynivalenol (DON) in grains. Extraction was carried out with aceronitrile-water mixture (84/16,V/V), followed by a clean-up step with TRILOGY columns. The extracts was analyzed by UV detector (λ = 220 nm) and C18 column. The results showed that using high-speed Homogenizer extracts 4 min, greatly increased the recovery rate(90.3%-102.1%),the lowest detection limits was 50 μg/kg.
