Two new stilbene glucosides [(+)-alpha-viniferin 13b-O-beta-glucopyranoside and resveratrol 12-C-beta-glucopyranoside] and two new resveratrol oligomers, hemsleyanols A and B, were isolated from the bark of Shorea hemsleyana along with four known resveratrol oligomers. The structures of the isolates, including the relative configurations, were established by spectroscopic data involving long-range coupling and nuclear Overhauser effect experiments.
从望天树的树皮中分离出两种新的芪糖苷[（+）-α-葡萄素13b-O-β-葡萄糖苷和白藜芦醇12-C-β-葡萄糖苷]以及两种新的白藜芦醇低聚物，即滇南木莲醇A和B，同时还分离出四种已知的白藜芦醇低聚物。通过涉及远程偶合和核Overhauser效应实验的光谱数据确定了分离物的结构，包括相对构型。
