Abstract

Eight new oleanane-type triterpenoid saponins, named schefflesides A-H (1-8), were isolated from the aerial parts of Schefflera kwangsiensis. The structures of these new compounds were established on the basis of hydrolysis and spectroscopic evidence, including 1D- and 2D-NMR (HSQC, HMBC, ROESY and TOCSY) and HR-MS analyses.
