摘      要：To investigate the saponins from whole plants of Lysimachia capilUpes 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-L-arabinpyranoyl]-22-O-β-D-glucopyranoside （1） and 3β, 22α-dihydroxy- 16α-acetat-28→ 13-lactone-oleanane-3-O-{ [β-D-glucopyranosyl-（1→2）-β-D-glucopyranosyl-（1→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.
