白木香果实化学成分研究

Studies on Chemical Constituents from Fruits of Aquilaria sinensis

摘要:

运用柱色谱技术从白木香(Aquilaria sinensis (Lour.) Gilg)果实中分离得到7个化合物,经波谱解析和理化性质分别鉴定为: 3-吲哚甲酸(1)、6-羟基-2-[2-(4-羟基苯基)乙基]色原酮(2)、芫花素(3)、4', 5-二羟基-3',7-二甲氧基黄酮(4)、洋芹素-7,4'-二甲醚(5)、 β-谷甾醇(6)和胡萝卜苷(7)。其中化合物1为首次从瑞香科沉香属植物中分离得到。

Abstract:

Seven chemical constituents from fruits of Aquilaria sinensis (Lour.) Gilg were isolated by column chromatography. Based on spectral analysis and physicochemical evidence, their structures were identified as: indolyl-3-carboxylic acid (1), 6-hydroxy-2-[2-(4-hydroxyphenyl)ethyl] chromone (2), genkwanin (3), 4',5-dihydroxy-3',7-dimet-hoxyflavone (4), apigenin-7,4'-dimethylethers (5), β-sitosterol (6), and daucosterol (7). Compound 1 was obtained from the genus Aquilaria of the family Thymelaeaceae for the first time.
