A new triterpenoid saponin, named segetoside k, has been isolated from the seeds of Vaccaria segetalis. On the basis of chemical reaction and spectral analysis, the structure of segetoside K was established as:olean-12-ene-23α, 28b-dioic acid 3b, 16a-dihydroxy-28-O-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyra-nosyl-(1→2)-β-D-glucopyranosyl-(1→6)-β-D-gluco-pyranoside(1).
- Vaccaria segetalis,
- Triterpenoid saponin,
- Segetoside K
