Abstract

The presence of indoleacetaldehyde in cucumber (Cucumis sativus L.) cotyledons was demonstrated by thin layer chromatographic R(F) values in three solvent systems, by the formation and hydrolysis of a bisulfite adduct, and by chemical reduction to indoleethanol and oxidation to indoleacetic acid. Bioassays indicated a minimum indoleacetaldehyde content in etiolated cotyledons of 0.7 mug per kg fresh weight. Tissue samples from all parts of both green and etiolated cucumber seedlings reduced exogenously supplied indoleacetaldehyde to indoleethanol.

摘要

黄瓜(Cucumis sativus L.)子叶中吲哚乙醛的存在通过三种溶剂系统中的薄层色谱 R(F) 值、亚硫酸氢盐加成物的形成和水解以及化学还原为吲哚乙醇和氧化为吲哚乙酸来证明。生物测定表明,黄化子叶中吲哚乙醛的最低含量为每公斤鲜重 0.7 微克。来自绿色和黄化黄瓜幼苗所有部位的组织样本将外源性供应的吲哚乙醛还原为吲哚乙醇。
