Three new triterpenoid saponins, named segetoside G (1), H (2) and I (3), have been isolated from the seeds of Vaccaria segetails. On the basis of chemical reaction and spectral data, their structures have been established as: 28-O-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-[α-L-arabinofuranosyl (1 → 3)]-β-D-(4-O-acetyl)-fucopyranosyl-gypsogenin-3-O-β-D-gal-actopyranosyl-(1 → 2)-β-D-(6-O-butyl ester)-glucuronopyranoside (1), 28-O-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-[α-L-(5-O-acetyl)-arabinofuranosyl-(1 → 3)]-β-D-(4-O-acetyl)-fucopyranosyl-gypsogenin-3-O-β-D-galactopyranosyl-(1 → 2)-β-D-glucuronopyranoside (2) and 28-O-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-[α-L-(5-O-acetyl)-arabinofuranosyl-(1 → 3)]-β-D-(4-O-acetyl)-fucopyranosyl-quillaic acid-3-O-β-D-galactopyranosyl-(1 → 2)-β-D-glucuronopyranoside (3).
