A new indole-3-acetic acid metabolite was isolated from broad bean (Vicia faba L. cv Chukyo) seedlings. It was a conjugate of dioxindole-3-acetic acid, aspartic acid, and glucose and was identified as 3-(O-beta-glucosyl)-2-indolone-3-acetylaspartic acid (molecular weight 484) from ultraviolet, infrared, nuclear magnetic resonance, and mass spectra. Its natural content in 4-day-old Vicia seedlings was estimated to be 8.6 nanomoles per gram fresh weight. It was suggested that oxidation of indole-3-acetic acid not accompanied by decarboxylation might regulate endogenous level of the hormone.
从蚕豆(Vicia faba L. cv Chukyo)幼苗中分离到一种新的吲哚-3-乙酸代谢物。它是二氧吲哚-3-乙酸、天冬氨酸和葡萄糖的轭合物,根据紫外、红外、核磁共振和质谱确定为 3-(O-β-葡萄糖基)-2-吲哚酮-3-乙酰天冬氨酸(分子量 484)。4 日龄蚕豆幼苗中其天然含量估计为每克鲜重 8.6 纳摩尔。这表明吲哚-3-乙酸的氧化不伴随脱羧可能调节激素的内源性水平。
