profiling studies using HPLC-ESI-MS-MS. The catabolites, namely [7′,7′,7′-d3]-PA, [7′,7′,7′-d3]-DPA, [5,8′,8′,8′-d4]-7′-hydroxyABA and [4,5,8′,8′,8′-d5]-ABA glucose ester were prepared either by biotransformation or chemical synthesis starting with labelled ABA. The labelled compounds are employed as internal standards for plant hormone profiling by liquid chromatography–electrospray–tandem mass spectrometry
使用 HPLC-ESI-MS-MS 制备了四种氘标记的高同位素纯度 ABA 分解代谢物,用于激素分析研究。分解代谢物,即[7',7',7'-d3]-PA, [7',7',7'-d3]-DPA, [5,8',8',8'-d4]-7 '-羟基ABA 和[4,5,8',8',8'-d5]-ABA 葡萄糖酯是通过生物转化或化学合成从标记的 ABA 开始制备的。标记的化合物用作通过液相色谱-电喷雾-串联质谱法进行植物激素分析的内标。版权所有 © 2005 John Wiley & Sons, Ltd.
