Additional Data for the Paperchromatographic Survey of Anthocyanins in the Flora of Japan (IV)

Previously, the anthocyanins contained in Japanese plants were reported. The surveys were continued in this laboratory, and the results obtained in these years are to be presented, while 84 plants, wild and cultivated, were investigated paper- chromatographically. About 250 plants, including these 84 ones, were known to contain one or two kinds of anthocyanidins, although the nature of their glycosides were not satisfactorily determined. The number of plants hitherto examined nearly attained a quarter of the whole anthocyanin-containing, flowering plants belonging to the flora of Japan.
