Abstract

Eleven previously undescribed triterpene saponins, named silenegallisaponin A-K (1 – 11), were isolated from the aerial parts of Silene gallica L. Their structures were elucidated by analysis of 1D and 2D-NMR spectroscopic data and mass spectrometry (HR-ESI-MS). The saponins comprised caulophyllogenin, echinocystic acid, or quillaic acid substituted at C-3 by a β - d -glucuronic acid or β - d -galactopyranosyl-(1 → 3)- β - d -glucuronopyranoside and at C-28 by a β - d -fucopyranose substituted at C-2 by a β - d -glucose and at C-3 by a β - d -glucose or a β - d -quinovose. Image 1 • Eleven undescribed triterpenoid saponins were isolated from Silene gallica L. • Their structures were elucidated by 1D, 2D-NMR and HRESIMS analyses. • A chemotaxonomic significance is given in the conclusion.
