Abstract

•Chemical constituents of aerial parts of Schefflera kwangsiensis were investigated.•Eight new oleanane-type triterpenoid saponins (1–8) were isolated.•The structures of the new compounds were elucidated by spectroscopic methods and acid hydrolysis.•The saccharide chains linked to C-28 of oleanolic acid in compounds 1–5 were selectively acetylated.

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.
