A new triterpenoid saponin, named segetoside L, was isolated from the seeds of Vaccaria segetalis. On the basis of spectral data and chemical reaction, its structure was established as 28-O-b-D-glucopyranosyl-(16)-b-D-glucopyranosyl oleanolic acid 3-O-b-D- glucopyranosyl-(13)-[b-D-galactopyranosyl-(12)]-b-D-galactopyranoside.
