3-O-β-D-Glucopyranosyltheobroxide from Aerial Parts of Cowpea (Vigna unguiculata)

Abstract

Theobroxide has been isolated from culture filtrates of Lasiodiplodia theobromae as a potato tuber-inducing compound. In this study, the metabolism of theobroxide was investigated using cowpea as an experimental model and [ 2 H 3-7]theobroxide as a substrate for analyzing a metabolite, which revealed that theobroxide applied exogenously to the roots was converted into 3-O--D-glucopyranosyltheobroxide.
