Abstract

A new ursane-type triterpenoid (1), together with 15 known compounds (2–16), was isolated from the barks of Schefflera heptaphylla (L.) Frodin. The structure of the new compound was determined on the basis of extensive spectroscopic data including IR, HR-ESI-MS, 1D and 2D NMR, and further confirmed by single-crystal X-ray diffraction. Compounds 2–6 were isolated from Schefflera genus for the first time.
