To investigate the saponins from whole plants of Lysimachia capillipes Hemsl., two new saponins, named capilliposide E (1) and capilliposide F (2), were isolated. The structures of the new saponins were elucidated as 3β,22α‐dihydroxy‐16α‐acetat‐28→13‐lactone‐oleanane‐3‐O‐[β‐D‐glucopyranosyl‐(1←2)‐α‐Z‐arabinpyranoyi]‐22‐O‐β‐D‐glucopyranoside (1) and 3β, 22α‐dihydroxy‐16α‐acetat‐28‐l3‐lactone‐oleanane‐3‐O‐{[β‐D‐glucopyranosy‐(l→2)‐β‐D‐glucopyranosyl‐(l→4)]‐α‐L‐arabinpyranoyl}‐22‐O‐β‐D‐glucopyranoside (2). The structures of these compounds were determined by 1D‐ and 2D‐NMR, MS techniques, and chemical methods. (Managing editor: Wei WANG)
