摘 要 ：从白木香(Aquilaria sinensis (Lour.) Gilg)树干的乙醇提取物中分离得到5个黄酮类化合物，经波谱分析，分别鉴定为：洋芹素-7,4′-二甲醚(1)、5-羟基-7,3′,4′-三甲氧基黄酮(2)、木犀草素-7,4′-二甲醚(3)、芫花素(4)和4′,5-二羟基-3′,7-二甲氧基黄酮(5)。以上化合物均为首次从该种植物树干中分离得到。

Abstract:Five flavones were isolated from the ethanol extraction of the stem of Aquilaria sinensis. On the basis of spectral analysis, their structures were elucidated as: apigenin-7,4′-dimethylethers (1), 5-hydroxyl-7,3′,4′-trimethoxyflavone (2), 7,4′-dimethyl -luteolin (3), genkwanin (4) and 4′,5-dihydroxy-3′,7-dimethoxyflavone (5). All the compounds were isolated from the stem of this species for the first time.
