从白藜芦醇茎的丙酮可溶部分中分离得到4个新的白藜芦醇衍生物：白藜芦醇B(1)，C(4)，D(5)(白藜芦醇四聚体)和E(6，白藜芦醇二聚体，含C-6-C-1单元)，以及9个已知的白藜芦醇低聚物和白藜芦醇。通过波谱分析，包括一维和二维核磁共振实验，确定了新化合物的结构。
Four new resveratrol derivatives, upunaphenols B (1), C (4), D (5) (resveratrol tetramer) and E (6, resveratrol dimer with a C-6-C-1 unit), together with nine known resveratrol oligomers and resveratrol were isolated from an acetone soluble part of stem of Upuna borneensis (Dipterocarpaceae). The structures of new compounds were determined by spectral analysis including 1D and 2D NMR experiments.
