目的 研究野生白木香Aquilaria sinensis叶的化学成分.方法 采用硅胶柱色谱等方法进行分离纯化,根据理化性质和波谱解析鉴定化合物结构.结果 从野生白木香叶70%丙酮渗漉提取物中分离得到13个化合物,分别鉴定为反-6-十八烯酸(1)、亚油酸乙酯(2)、洋芹素-7,4'-二甲醚(3)、4-氰基苯甲醛(4)、木犀草素-7,3',4'-三甲醚(5)、芫花素(6)、对苯二甲酸二(4-辛)酯(7)、6-羟基-7,4'-二甲氧基黄酮(8)、5-羟基-7,2',4',5'-四甲氧基黄酮(9)、5,4'-二羟基-7,3'-二甲氧基黄酮(10)、槲皮素(11)、山柰酚(12)、对羟基苯甲酸(13).结论 化合物4、8、9为首次从瑞香科植物中分离得到.
Chemical constituents from leaves of wild Aquilaria sinensis
Objective To investigate the chemical constituents from the leaves of wild Aquilaria sinensis.Methods The powder of the dried leaves was percolated with 70% acetone.Various chromatographic methods were employed to isolate the compounds and their structures were established by spectroscopic analysis.Results Thirteen compounds were isolated and identified as 6-E-octadecenoic acid (1),ethyl linoleate (2),apiolin-7,4'-dimethyl ether (3),4-cyanobenzaldehyde (4),luteolin-7,3',4'-trimethyl ether (5),genkwanin (6),p-phthalic acid di (4-octyl) ester (7),6-hydroxy-7,4'-dimethoxyflavone (8),5-hydroxy-7,2',4',5'-tetramethoxyflavone (9),5,4'-dihydroxy-7,3'-dimethoxyflavone (10),quercetin (11),kaempferol (12),and 4-hydroxybenzoic acid (13).Conclusion Thirteen compounds have been identified from wild A.sinensis leaves.Compounds 4,8,and 9 are firstly isolated from the plants of Thymelaeaceae.
