Résumé
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.
