摘要
目的研究药用红树植物角果木(Ceriops tagal)的化学成分。方法采用硅胶柱色谱和Sephadex LH-20凝胶柱色谱从角果木胚胎的乙醇提取物中分离到7个化合物,经理化常数和波谱分析确定其结构。结果这7个化合物分别为:β-谷甾醇(Ⅰ)和豆甾醇(Ⅱ)的混合物、桦木醇(Ⅲ)、3-表白桦脂酸(Ⅳ)、3-表乙酸酯白桦脂酸(Ⅴ)、咖啡酸(Ⅵ)和5,7,3′,4′-四羟基黄酮醇(Ⅶ)。结论以上化合物均为首次从该种植物中分离得到。
Abstract
OBJECTIVE To study the chemical constituents of the embryo of Ceriops tagal.METHODS The compounds were isolated and purified by using column chromatography with silical gel and Sephadex LH-20,and their structures were identified by their physical and spectral data. RESULTS Seven compounds were isolated and elucidated as the mixture of β-sitosterol(Ⅰ) and stigmasterol(Ⅱ),betulin(Ⅲ),3-epi-butulinic acid(Ⅳ),3-epi-acetylbetulinic acid(Ⅴ),caffeic acid(Ⅵ) and 5,7,3′,4′-tetrahydroxyflavonol(Ⅶ).CONCLUSION All the compounds are firstly isolated from this species.
