Two isoflavonoids isolated from Dalbergia sympathetica were identified as 5,4'-dihydroxy-7-methoxyisoflavone (1) (Prunetin) and Prunetin-4'-O-beta-D-gentiobioside (2) (Dalsympathetin). The natural occurrence of Dalsympathetin is reported for the first time. The position of glycosylation in Dalsympathetin at 4'-position has been confirmed by 2D-NMR spectral studies.
从交感黄檀中分离出的两种异黄酮被鉴定为5,4'-二羟基-7-甲氧基异黄酮(1)(樱黄素)和樱黄素-4'-O-β-D-龙胆二糖苷(2)(交感黄檀苷)。交感黄檀苷的天然存在首次被报道。通过二维核磁共振光谱研究确定了交感黄檀苷中糖基化位于4'-位。
