Abstract:
AIMTo study the triterpenoid saponins in the whole plants of Lysimachia capillipes Hemsl..
METHODSColumn 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.
RESULTSTwo new triterpenoid saponins were isolated and established as 3beta, 22alpha-dihydroxy-16alpha-angeloyloxy-28-->13-lactone-oleanane-3-O-[beta-D-glucopyranosyl-(1-->2)-alpha-L-arabinpyranosyl]-22-O-(6-acetyl)-beta-D-glucopyranoside (I), 3beta, 13beta, 22alpha-trihydroxy-16alpha-acetyloxyoleanane-28-oic acid Na-3-O-[beta-D-glucopyranosyl-(1-->2)-alpha-L-arabinpyranosyl]-22-O-beta-D-glucopyranoside (II).
CONCLUSIONCompounds I and II are new compounds and named as capilliposide I and capilliposide J.
