摘　　要：目的:研究小鱼眼草全草(Dichrocephala benthamii Clarke)化学成分。方法:采用硅胶、AB-8大孔树脂和Sephadex LH-20等色谱手段进行分离纯化,通过理化方法、光谱分析及文献对照鉴定化合物结构。结果:分离出7个化合物,鉴定出其中4个,分别为没食子酸(Ⅱ),山奈酚(Ⅵ),邻苯二甲酸二丁酯(Ⅴ),槲皮素(Ⅶ)。结论:除化合物邻苯二甲酸二丁酯(Ⅴ)外,其他三种均为首次从小鱼眼草中分离纯化出。Objective To study Dichrocephala benthamii Clarke chemical composition. Methods The Dichrocephala benthamii Clarke chemical composition were purified by silica gel, AB - 8 macroporous resin and Sephadex LH - 20 and at last identified by spectrum analysis and reference. Results seven compounds were purified from Dichrocephala benthamii Clarke and four compounds were identified, they are Gallic acid （ Ⅱ ）, Kaempferol （ Ⅵ）, Dibutyl phthalate （ Ⅴ ）, Quercetin （Ⅶ）. Conclusion identified compound were frist time purified from Dichrocephala benthamii Clarke except Dibutyl phthalate Dibutyl phthalate （ Ⅴ ）.
