摘要
目的:研究水红花子(Polygonum orientale L.)的化学成分。方法:利用系统溶剂提取法、正相和反相硅胶柱色谱法、制备HLPC法进行分离和纯化,采用谱学技术(NMR、MS、UV等)进行结构鉴定。结果:从水红花子乙酸乙酯部位分离得到3,5,7-trihydrochromone(Ⅰ)、kaempferol(Ⅱ)、5,7,4′-trihydroxydihy-droflavonol(Ⅲ)、3-pyridine carboxylic acid(Ⅳ)、5-dimethoxy-4-hydroxybenzoic acid(Ⅴ)5个化合物,其中化合物Ⅲ-Ⅴ首次从该植物中分离得到。
Objective：To Study on the chemical constituents in the cane part of polygonum orientale L.Methods：The compounds were isolated by the solvent extraction , silica gel ,and reversed-phase silica gel column chromatography and semi-preparative HLPC chromatography. The structures were identified by various spectroscopic methods including NMR spectrum, MS , UV, etc .Results-Five aromatic compounds were isolated and purified from the ethyl acetate fraction and identified as 3,5,7-trihydrochromone （ Ⅰ ）,kaempferol （ Ⅱ ）,5,7,4＇-trihydroxydihy-droflavonol （ Ⅲ ）3-pyridine carboxylic acid （Ⅳ）5-dimethoxy-4-hydroxybenzoic acid （Ⅴ） .Conclusion： Compouds 3-5were obtained from the plant for the first time.
