| Abstract: | From the leaves of Schefflera sessiliflora De P. V., two new oleanane-type triterpene saponins, named scheffleraside A (1), scheffleraside B (2); together with two known saponins, chikusetsusaponin IVa (3), 3-O-[α-l-rhamnopyranosyl-(1 → 3)]-β-d-glucuronopyranosyl hederagenin (4) were isolated by various chromatography methods. Its chemical structure was elucidated by IR, UV, HR-ESI-MS, NMR 1D and 2D experiments and comparison of their NMR data with previous reported data. |
