Arboreasides A−E, Triterpene Saponins from the Bark of Cussonia arborea
2009
Five new triterpene saponins, arboreasides A-E (1-5), and two known saponins, ciwujianoside C(3) and 23-hydroxyursolic acid 28-O-alpha-L-rhamnopyranosyl-(1--4)-beta-D-glucopyranosyl-(1--6)-beta-D-glucopyranosyl ester, were isolated from the bark of Cussonia arborea. The structures were established using extensive 1D and 2D NMR spectroscopic analyses and mass spectrometry.
Isolation and caracterisation of saponins from three plants of Araliaceae and Dracaenaceae families and evaluation of their cytotoxic activities on t…
2010
The interest of the substances from natural origin, potentially antitumor led us to interest in triterpenoid and steroidal saponins of plants from the African biodiversity belonging to the Araliaceae and Dracaenaceae families of plants. Indeed, of the former studies undertaken on some plants of these two families led to obtaining complex and original molecules having excellent cytotoxic, immuno-modulating, anti-inflammatory properties. Within sight of these results we undertook pharmaco-chemical investigations on Cussonia arborea (Araliaceae), Dracaena deisteliana, and Dracaena arborea (Dracaenaceae), medicinal plants usually used in african traditional pharmacopeia to treat various disease…
Bafouoside C, a new triterpenoid saponin from the roots of Cussonia bancoensis Aubrev. & Pellegr.
2014
Abstract A new triterpenoid saponin named bafouoside C 3-O-β- d -glucopyranosyl-(1 → 4)-[β- d -galactopyranosyl-(1 → 2)]-β- d -glucuronopyranosyloleanolic acid 28-O-β- d -glucopyranosyl ester; (1), together with five known compounds 3-O-β- d -galactopyranosyl-(1 → 2)-β- d -glucuronopyranosyloleanolic acid (2), 23-hydroxyursolic acid (3), 28-O-α- l -rhamnopyranosyl-(1 → 4)-O-β- d -glucopyranosyl-(1 → 6)-O-β- d -glucopyranosyl-23-hydroxyursolic acid (4), 3-O-β- d -glucopyranosyl-23-hydroxyursolic acid (5), and 3-O-α- l -arabinopyranosyl-23-hydroxyursolic acid (6), were isolated from the roots of Cussonia bancoensis Aubrev. & Pellegr. Their structures were established on the basis of 1D- and 2…
