Two kinds of steroidal sapogenins were isolated from the bulb of Polianthes tuberosa L. (Amaryllidaceae). One is the chief component, melts at 265°, and gives an acetate of m.p. 243-245°, and a 2, 4-dinitrophenylhydrazone of m.p. 275°. Admixture of the genin and its acetate respectively with hecogenin and its acetate showed no depression of the melting point. Further, its chemical properties, analytical values, and infrared absorption spectrum all agreed with those of hecogenin. The other, obtained in a small amount, showed m.p. 207° and the admixture of the genin and its acetate with tigogenin and its acetate showed no depression of the melting point.
