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

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。

Abstract

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

5 and 6 were obtained from P.capitatum for the first time.Compound 2 and 7 were obtained from Polygonaceae for the first time.
