目的研究鬼箭羽的化学成分。方法采用溶剂法和色谱法进行分离纯化,通过理化性质、光谱数据的解析进行结构鉴定。结果分离并鉴定的9个化合物分别为β-谷甾醇(Ⅰ)、木栓醇(Ⅱ)、木栓酮(Ⅲ)、松萝酸(Ⅳ)、羽扇豆酮(Ⅴ)、白桦脂醇(Ⅵ)、齐墩果酸(Ⅶ)、正二十六烷酸(Ⅷ)和正二十八烷醇(Ⅸ)。结论化合物Ⅴ~Ⅷ均为首次从鬼箭羽中分离获得。 Objective To study the chemical composition of ghost arrows. Methods Solvent and chromatographic methods were used for the separation and purification. The structures were elucidated by physicochemical properties and spectral data analysis. Results Nine compounds isolated and identified were β-sitosterol (Ⅰ), cilosolol (Ⅱ), woodpox (Ⅲ), usnic acid (Ⅳ), lupine (Ⅴ), betulin Ⅵ), oleanolic acid (Ⅶ), n-hexacosanoic acid (Ⅷ) and n-octacosanol (Ⅸ). Conclusion Compounds Ⅴ ~ Ⅷ were isolated from the ghost feather for the first time.
