十雄角果木树皮的化学成分研究

Chemical constituents of the barks of Ceriops decandra

通过溶剂提取法、正反相硅胶柱色谱和高效液相色谱等方法,从十雄角果木(Ceriops decandra)树皮的95%乙醇提取物中分离得到了6个单体化合物,并通过理化性质和波谱数据鉴定其结构,分别为:(-)-丁香树脂酚(1),(-)-松脂酚(2),β-谷甾醇(3),豆甾醇(4),棕榈酸(5)和3,4-二羟基苯甲酸乙酯(6).所有化合物均为首次从该植物中分离得到.

Six compounds were isolated from the chloroform extract of the 95％ ethanol extract of the barks of Ceriops decandra.Different chromatographic methods,including column chromatography and HPLC were used.The structures of these compounds were identified by means of spectroscopic data and physicochemical properties,and assigned as （-）-syringaresinol （1）,（-）-pinoresinol （2）,β-sitosterol （3）,stigmasterol （4）,palmitic acid （5）,and 3,4-dihydroxybenzoic acid ethyl ester （6）.All the above compounds were obtained from this plant for the first time.
