摘    要:本文研究建立了高效液相色谱-电感耦合等离子体质谱(HPLC-ICP-MS)联用检测转基因大豆中的硒酸盐(Se VI)、亚硒酸盐(Se IV)、硒代蛋氨酸(selenomethionine,Se Met)、硒代胱氨酸(selenocystine,Se Cys2)和硒代乙硫氨酸(selenoethionine,Se Et)的方法。探讨了色谱柱、流动相及其酸度对分离效果的影响,使用10 mmol/L的柠檬酸溶液(p H值4.5)作流动相,Hamilton PRP X-100色谱柱分离,碰撞反应池技术消除40Ar40Ar+和40Ar2H2+等多原子离子干扰,ICP-MS检测82Se同位素,在21 min内可完全分离检测5种硒形态。探讨了不同提取方法的提取效果,优化了提取条件,采用蛋白酶提取,针对美国进口的转基因大豆样品进行加标回收实验,结果表明采用蛋白酶提取,Se IV和Se VI的回收率在100%左右,Se Met的回收率在92.6%~109.3%之间,Se Cys2和Se Et的回收率为81.2%~95.9%。该方法可完全满足转基因大豆中的硒形态定量分析鉴定。

关 键 词:转基因大豆  硒形态  HPLC-ICP-MS
