1) Paper chromatography of dioscin and several of its allied compounds was examined. It was thereby found that by the use of developing solvent and coloring agents listed in Table I, isolation and detection of dioscin was possible and that some assumptions could also be made on the presence of a minute amount of other new saponins.
2) This method of paper chromatography was carried out on the water-insoluble saponins from Dioscorea nipponica, D. gracillima, and D. tenuipes, described in the previous report, on the dioscin sample of Tsukamoto and Ueno, on each of the (A), (B), and (C) fractions from the chromatographic purification of these samples, and on purified saponins. It was thereby found that both the crude products and the samples were chiefly dioscin but contained a minute amount of unknown substance. The saponin from D. gracillima was found to contain, besides the above, a small amount of a new substance. Each of the (A) fractions was composed only of dioscin, while the (B) fraction from D. gracilliama was composed of the new substance. The purified products were all found to be pure dioscin.
