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。
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.
