    Quantitative Analysis of Fatty Acids from Safflower by Selective and Sensitive Pre-Column Derivatization Method Using HPLC-FLD and Online APCI/MS
    摘要:
    一种预柱衍生化方法被成功开发,使用2-(11H-苯并[a]喹唑-11-基)乙基4-甲基苯磺酸酯(BCETS)作为标记试剂,随后通过高效液相色谱(HPLC)结合荧光检测以及在线APCI/MS,对来自红花的脂肪酸进行定量分析。脂肪酸可以在95°C的条件下,在DMF中加入K2CO3作为催化剂,在35分钟内轻松快速地被BCETS标记。衍生物表现出优异的荧光特性,激发波长为272nm,发射波长为505nm。该方法显示出良好的选择性、灵敏度、重现性和适用性。对在青海省不同地点种植的青海和新疆红花(QHS和XJS)进行了分析。结果显示,青海红花样品的总脂肪酸、饱和脂肪酸和不饱和脂肪酸含量均远高于新疆红花样品,尤其是种植在大通县的青海红花样品。主要的不饱和脂肪酸为C18:1、C18:2和C18:3,而主要的饱和脂肪酸分别为C16、C18和C20。这项工作将有助于对两种红花的安全评估和质量控制。
