Triterpene saponins from Silene gallica collected in North-Eastern Algeria

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.
