An improved method of fractionating the myoinositol esters of indoleacetic acid (IAA) from maize kernels by gas-liquid chromatography has been developed. Mass spectrometry was employed as an aid in identification of the esters. Maize kernels contain three groups of esters of IAA: (a) IAA myoinositols, (b) IAA myoinositol arabinosides, and (c) IAA myoinositol galactosides. Each group has three chromatographically distinguishable isomers. The glycosylinositols described are unique in that carbon 1 of the sugar is attached to the hydroxyl at C-5 of the myoinositol.
已经开发出一种改进的方法，通过气液色谱法从玉米籽粒中分离吲哚乙酸（IAA）的肌醇酯。质谱法被用作鉴定酯的辅助手段。玉米籽粒中含有三组 IAA 的酯：（a）IAA 肌醇，（b）IAA 肌醇阿拉伯糖苷，和（c）IAA 肌醇半乳糖苷。每组有三个在色谱上可区分的异构体。所描述的糖肌醇是独特的，因为糖的碳 1 连接到肌醇的 C-5 上的羟基。
