Diosgenin, kryptogenin, and yamogenin are known as the sapogenins obtained from the plants of Dioscoreaceae but only diosgenin alone has been found in Dioscorea tokoro Makino. A small amount of crystals of m.p. 266°, [α]D: -49.6° (EtOH), was isolated from the rhizome of D. tokoro, besides diosgenin, and various reactions were carried out on this substance. As a result, it has been confirmed that this substance is an unknown iso-type trihydroxysteroidal sapogenin and was designated as tokorogenin.
