Steroidal saponins from Lysimachia Paridiformis

Abstract

A new steroidal saponin, paridiformoside B (1), was obtained from the EtOH extract of the whole plant of Lysimachia Paridiformis Franch, togerher with one steroidal sapogenin (7) and seven known steroidal saponins (2-6, 8-9). Their structures were elucidated using extensive spectroscopic techniques including 1D and 2D NMR spectra.
