Abstract

A new enzymatic activity, which catalyses formation in vitro of di-O-(indole-3-acetyl)-D-glucose from 1-O-(indole-3-acetyl)-beta-D-glucose has been found in extracts of Zea mays seedlings. The structure of di-O-(indole-3-acetyl)-D-glucose, not as yet described, has been assigned by GC-MS, 1H NMR and ammonolysis.

摘要

在玉米幼苗提取物中发现了一种新的酶活性，该酶能在体外催化由1-O-(吲哚-3-乙酰基)-β-D-葡萄糖形成二-O-(吲哚-3-乙酰基)-D-葡萄糖。二-O-(吲哚-3-乙酰基)-D-葡萄糖的结构尚未见报道，已通过气相色谱-质谱联用仪、核磁共振氢谱和氨解反应进行了确定。
