Identification of 3-(O--Glucosyl)-2-Indolone-3-Acetylaspartic Acid as a New Indole-3-Acetic Acid Metabolite in Vicia Seedlings

Biological Institute, Faculty of Science, Tohoku University, Sendai 980 Japan

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--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.
