We prepared deuterium-labeled 5-deoxystrigol (5DS), a multifunctional plant second metabolite, using a simple set of procedures. The labeled compound contained mainly [3a,4,4,5,5,6′-D6]-5DS and [D5]-5DS and did not contain unlabeled 5DS. Therefore, multideuterated 5DS can be used as an internal standard in liquid chromatography/mass spectrometry (LC/MS) assays to quantitate the amounts of 5DS in plants and root exudates.

我们采用一套简单的程序制备了氘标记的多功能植物第二代谢产物--5-脱氧甾三醇(5DS)。标记的化合物主要含有[3a,4,4,5,5,6′-D6]-5DS和[D5]-5DS,不含未标记的5DS。因此,多氘代 5DS 可用作液相色谱/质谱(LC/MS)分析中的内标,以定量检测植物和根系渗出液中的 5DS 含量。Copyright © 2010 John Wiley & Sons, Ltd. All Rights Reserved.
