title: Steroidal saponins and pregnane glycosides from Smilax microphylla.
abstract: Six steroidal saponins and two pregnane glycosides were isolated from the BuOH subfraction of 70% EtOH extract of Smilax microphylla C.H.Wright, among them two were new compounds (1 and 7). Pregnane glycosides were firstly isolated from the genus Smilax (Smilacaceae). Structures of the new compounds were determined on the basis of HR-ESI-MS, 1D and 2D NMR spectroscopic analysis.
