A method for the analysis of indole-3-acetic acid (IAA) in plant extracts has been developed based on high performance liquid chromatography separation of IAA on a microparticulate strong anion exchange column followed by quantitation with two selective detectors: an electrochemical, carbon paste amperometric detector and/or a fluorescence detector. The detection limit for IAA is less than 1 nanogram with the fluorescence detector and less than 50 picograms with the electrochemical detector.The IAA levels are reported for various tissues of wheat, pinto beans, soybeans, cotton, and corn.
基于在微粒强阴离子交换柱上对吲哚 - 3 - 乙酸(IAA)进行高效液相色谱分离,随后使用两种选择性检测器进行定量分析,开发了一种用于分析植物提取物中IAA的方法:一种是电化学碳糊安培检测器,另一种是荧光检测器。使用荧光检测器时,IAA的检测限小于1纳克;使用电化学检测器时,检测限小于50皮克。报告了小麦、斑豆、大豆、棉花和玉米不同组织中的IAA水平。
