摘要：

Four new oleanane saponins, lobelioidosides A-D (1-4, resp.), all endowed with 16-oxo and a 23-OH group, as well as with a 13,28-epoxy bridge as a common moiety, have been isolated from the 75% EtOH extract of the whole plant of Lysimachia lobelioides. Their structures were elucidated on the bases of MS, H-1- and C-13-NMR, HMQC, HMBC, and H-1,H-1-COSY data analysis.
