摘要
目的:研究头花蓼的化学成分。方法:采用反复硅胶、葡聚糖凝胶、反相硅胶及MCI凝胶柱色谱等方法分离纯化头花蓼的化学成分,根据理化性质和波谱数据进行化合物的结构鉴定。结果:由头花蓼全草的乙醇提取物中分离鉴定了7个化合物,分别为二十四烷基-1,3-二醇(1),(24R)-cycloart-25-ene-3β,24-diol(2),大黄素(3),胡萝卜苷(4),1-O-丁基-β-D-吡喃甘露糖苷(5),2-O-丁基-β-D-呋喃果糖苷(6),2-O-丁基-α-D-呋喃果糖苷(7)。结论:化合物1,3,5,6为从头花蓼中首次分离得到。化合物2,7为从蓼科中首次分离得到。
Objective：To study the chemical constituents of Polygonum capitatum.Method： Compounds were isolated and purified repeatedly by silica gel,Sephadex gel,ODS C18 and MCI gel column chromatography.Their structures were identified by physical,chemical methods and spectral data.Result： Seven compounds were obtained form 80% ethanol extract of P.capitatum,and identified as tetracosane-1,3-diol（1）,（24R）-cycloart-25-ene-3β,24-diol（2）,emodin（3）,daucosterol（4）,1-O-butyl-β-D-mannopyranoside（5）,2-O-butyl-β-D-fructofuranoside（6） and 2-O-butyl-α-D-fructofuranoside（7）,respectively.Conclusion： Compounds 1,3,5 and 6 were obtained from P.capitatum for the first time.Compound 2 and 7 were obtained from Polygonaceae for the first time.
