Several new glycosides were isolated from digitalis seeds. Five substances, A-VI acetate, C-I', A-VII, B-II, and X1, were obtained as crystals, and four substances, B-III, C-II, A-VII', and B-III', were obtained as a colorless powder. In accordance with their colorations and absorption spectra, it was assumed that A-VI, A-VII', B-III, and B-III' belong to gitoxigenin series, C-I' and C-II to digitoxigenin series, and B-II to digitanol series.
