Two new triterpenoid saponins from Lysimachia davurica

To study the triterpenoid saponins in the whole plant of Lysimachia davurica Ledeb. Column chromatography (including AB-8 macroporous resin, silica gel and ODS) was used to separate triterpenoid saponins whose structures were elucidated by ESI-MS, NMR (1D and 2D) and hydrolysis methods. Two new trit...

Summary:To study the triterpenoid saponins in the whole plant of Lysimachia davurica Ledeb. Column chromatography (including AB-8 macroporous resin, silica gel and ODS) was used to separate triterpenoid saponins whose structures were elucidated by ESI-MS, NMR (1D and 2D) and hydrolysis methods. Two new triterpenoid saponins were isolated and established as 3beta, 16alpha, 28-trihydroxy-olean-12-en-3-0-(beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucuronopyranosyl)-28-0-beta-D-glucopyranoside) (I), 3beta, 16alpha, 28-trihydroxy-olean-12-en-3-O-(beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucuronopyranosyl)-28-0-beta-D-glucopyranoside) (II). Compounds I and II are new compounds and named as davuricosides D and J.
