基于柱前衍生-超高效液相色谱-质谱联用技术的植物提取液中氨基化合物代谢谱分析

, 2015
氨基化合物在植物生长发育中起着重要作用。本文建立了一种基于柱前衍生-超高效液相色谱-质谱联用技术的植物提取液中氨基化合物代谢谱的分析方法。以烟草鲜叶为例,共检测出87种氨基化合物。其中43种氨基化合物的定量分析结果表明,方法的线性相关系数在0.993-0.999之间,线性范围可达到4个数量级,检出限为0.03-6.58 ng/mL,日内、日间精密度分别为0.7%-15.6%、0.8%-22.9%,回收率为74.4%-122.7%。采用该方法考察了打顶对不同部位烟草鲜叶中氨基化合物代谢谱的影响 ...

径向色谱柱用金属螯合亲和膜色谱介质的合成方法

, 1998
径向色谱柱用金属螯合亲和膜色谱介质的合成方法是利用甲基丙燃酸环氧丙酯进行自聚反应制得聚合物后与棉纤维进行接枝反应，然后与亚氨二乙酸进行开环反应，最后过渡金属离子进行螯合反应。该方法利用的原料便宜易得，反应条件简单，易控制，制得的螯合介质的结合容量大。应用该介质填充的径向色谱柱对人血清白蛋白、过氧化氢酶、尿激酶等生物大分子进行分离纯化处理，具有处理量大、流速快、纯化倍数高、便于线性放大等优点 ...
