摘　　要：目的研究鬼针草的化学成分。方法采用乙醇提取,硅胶柱、聚酰胺柱层析分离纯化,波谱分析鉴定其结构。结果从鬼针草中得到5个化合物:异槲皮苷(Ⅰ),异奥卡宁-7-O-β-D-葡糖苷(Ⅱ),海生菊苷(Ⅲ),槲皮素-7-O-β-D-葡糖苷(Ⅳ),D-甘露醇(Ⅴ)。结论5个化合物中的Ⅳ、Ⅴ是首次从本属植物中得到的。Objective To investigate the chemical compositions from Bidens bipinnata L. Methods Bidens bipinnata L. was extracted with ethanol, separated and purified by silica gel-polyamide column chromatography, then, the chemical structures of products were identified by spectral analysis. Results Five compounds were obtained： i soquercitrin（ Ⅰ ）, isookanin-7-O-β-D-glucoside（ Ⅱ ）, maritimetin（ Ⅲ ）, quercetin-7-O-β-D-glucoside（Ⅳ）, D-mannitol（Ⅴ ）. Conclusion Compound IV and V are first isolated from this plant.
