title: A new ursane-type triterpenoid from Schefflera heptaphylla (L.) Frodin.
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.
