For studying tannin substance contained in the leaves of Acer aizuense, the author applied the paper chromatography as a preliminary step. Two spots were detected with crude tannin extracted from leaves. One of the spots was recognized to agree with the spot by the colourless needle crystal obtained from crude tannin. Another spot was recognized to be given by gallic acid taken out of the decomposition product of the crystal (see Fig.1). Quercetin was also obtained from the mother liquor of the crude tannin.
