The aqueous extract of acetone powder, which had been prepared from Cornus capitata “Mountain Moon” adventitious roots, cultured in MS medium with a high concentration of Cu2+(10 μM), showed strong oxidative activity toward galloylglucoses. A compound formed from galloyglucoses, such as 1,2,3,4,6-penta-O-galloyl-β-D-glucose and tannic acid, by the reaction with the crude enzyme solution of the adventitious roots was isolated and characterized as ellagic acid by spectrometric analyses.
