Abstract: Six steroidal saponins were isolated from rhizome of Dioscorea tokoro Makino (collected from Zhejiang). By means of acetylation, acid hydrolysis, IR, MS, and 13C-NMR etc., five of them were identical with yononin (A) (yield 0.0069%), dioscin (C) (0.04%), gracillin (D) (0.03%), protodioscin (E) (0.5%), protogracillin (F) (0.2%), respectively. Because of low yield, saponin B was not identified.
Key words: Dioscorea tokoro, Steroidal saponins, yononin
