利用现代色谱分离技术对薄叶红厚壳Calophyllum membranaceum根的乙醇提取物氯仿部位进行分离纯化,得到8个化合物,分别鉴定为:木栓酮(Friedelin,Ⅰ)、海棠果醇(Canophyllol,Ⅱ)、木栓醇(Epi-friedelinol,Ⅲ)、3,4-二羟基苯甲酸(3,4-dihydroxybenzoic acid,Ⅳ)、穗花杉双黄酮(Amentoflavone,Ⅴ)、7-羟基香豆素(7-dihydroxycoumarin,Ⅵ)、紫花前胡苷(Marmesinin,Ⅶ)、紫花前胡苷元(Nodakenetin,Ⅷ)。其中化合物Ⅵ、Ⅶ、Ⅷ为首次从该植物中分离得到。 Eight compounds were isolated from the chloroform fraction of ethanol extract of Calophyllum membranaceum roots by modern chromatographic techniques. The compounds were identified as Friedelin Ⅰ, Canophyllol Ⅱ, Epi-friedelinol (Ⅲ), 3,4-dihydroxybenzoic acid (Ⅳ), Amentoflavone (Ⅴ), 7-dihydroxycoumarin Ⅵ), Marmesin (Ⅶ) and Nodakenetin (Ⅷ). The compounds Ⅵ, Ⅶ, Ⅷ were isolated from this plant for the first time.
