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 3β,22α-dihydroxy-16α-angeloyloxy-28→13-lactone-oleanane-3-O-［β-D-glucopyranosyl-(1→2)-α-L-arabinpyranosyl］-22-O-(6-acetyl)-β-D-glucopyranoside (I), 3β,13β,22α-trihydroxy-16α-acetyloxy-oleanane-28-oic acid Na-3-O-［β-D-glucopyranosyl-(1→2)-α-L-arabinpyranosyl］-22-O-β-D-glucopyranoside (II). ConclusionCompounds I and II are new compounds and named as capilliposide I and capilliposide J.
