银中杨树叶化学成分研究

Study on Chemical Constituents from the Leaves of Populus alba X P.berolinensis

采用硅胶柱色谱等分离方法,对银中杨Populus alba X P.berolinensis L.树叶的化学成分进行分离纯化,依据理化性质及波谱数据分析进行结构鉴定,从中分离鉴定了12个单体化合物,分别为:邻苯二酚(1),苯甲酸(2),水杨醇(3),东莨菪素(4),咖啡酸(5),水杨酸(6),2'-苯甲酰水杨苷(7),水杨苷(8),丁二酸(9),特里杨苷(10),3'-苯甲酰水杨苷(11)和6'-苯甲酰水杨苷(12),其中化合物3,4,7,9～12为首次从该植物中分离得到。

Twelve compounds were isolated from the leaves of Populus alba X P.berolinensis by silica gel column chromatography.On the basis of physicochemical properties and spectral analysis,their structures were identified as catechol（1）,benzoic aced（2）,salicylol（3）,scopoletin（4）,caffeic acid（5）,salicylic acid（6）,rtemuloidin（7）,salicin（8）,succinic acid（9）,tremulacin（10）,chaenomeloidin（11）,populin（12）.compounds 3,4,7,9-12 were isolated from P.alba X P.berolinensis for the first time.
