Aim To study the triterpenoid saponins in the whole plants of Lysimachia capillipes Hemsl. Methods 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 (1 D and 2D) and hydrolysis methods. Results Two new triterpenoid saponins were isolated and established as 3beta, 22alpha-dihydroxy-16alpha-angeloyloxy-28 fwdarw 13-lactone-oleanane-3-O-(beta-D-glucopyranosyl-(1 fwdarw 2)-alpha-L-arabinpyranosyl)-22-O-(6-acetyl)-beta-D-glucopyranoside (I), 3beta, 13beta, 22alpha-trihydroxy-16alpha-acetyloxy-oleanane-28-oic acid Na-3-O-(beta-D-glucopyranosyl-( 1 fwdarw 2)-alpha-L-arabinpyranosyl)-22-O-beta-D-glucopyranoside (II). Conclusion Compounds I and II are new compounds and named as capilliposide I and capilliposide J.
