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.
从七叶鹅掌柴（Schefflera heptaphylla (L.) Frodin）的树皮中分离出一种新的乌苏烷型三萜（1）以及15种已知化合物（2 - 16）。基于包括红外光谱（IR）、高分辨电喷雾电离质谱（HR-ESI-MS）、一维和二维核磁共振（1D和2D NMR）在内的大量光谱数据确定了新化合物的结构，并通过单晶X射线衍射进一步证实。化合物2 - 6首次从鹅掌柴属中分离得到。
