Triterpenoid saponins from Vaccaria segetalis.
A new triterpenoid saponin, named segetoside C (1), and two known saponins, vaccaroid A (vaccaroside A) (2) and dianoside G (3), have been isolated from the seeds of Vaccaria segetalis. On the basis of chemical reaction and spectral data, the structure of segetoside C (1) has been established as: gypsogenic acid-28-O-[beta-D-glucopyranosyl-(1-->3)]-[6-O-acetyl-beta-D-glucopyra-nosyl-(1-->2)-beta-D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside.
