A new benzophenone C-glycoside, malaferin A (1), and two new epicatechin derivatives, malaferin B (2) and malaferin C (3), together with five known compounds were isolated from Malania oleifera. In addition, (-)-epicatechin-3-O-benzoate (6) was isolated for the first time from a natural resource. Structures of 1-3 were determined on the basis of their spectroscopic methods, including 1D and 2D NMR techniques. All of the compounds were evaluated for anti-HIV activities.
从 Malania oleifera 中分离得到一个新的苯并二酮 C-糖苷马拉菲林 A（1），两个新的表儿茶素衍生物马拉菲林 B（2）和马拉菲林 C（3），以及 5 个已知化合物。此外，(-)-表儿茶素-3-O-苯甲酸酯（6）也是首次从天然资源中分离得到。根据光谱学方法，包括 1D 和 2D NMR 技术，确定了 1-3 的结构。所有化合物均进行了抗 HIV 活性评价。
