Isolation and Identification of Steroidal Saponins from Dioscorea parviflora Ting

Liu Cheng-lai, Chen Yan-yong and Ge Shao-bin   

Abstract: Four steroidal saponins were isolated from rhizomes of Dioscorea parvi- flora Ting collected from Yunnan Province. Their chemical structures have been elucidated by means of chemical and spectrometric analyses as gracillin [Ⅰ]; deltonine [Ⅱ]; protogracillin [Ⅲ] and deltoside [Ⅳ]. Deltoside is the first time obtained in pure state from Dioscorea plants.

Key words: Dioscorea parviflora Ting, Saponin, Steroidal saponin, Deltoside
