摘　　要：目的研究黄鹌菜的化学成分。方法采用硅胶柱色谱分离,用波谱学方法确定结构。结果从乙醇提取物的石油醚和醋酸乙酯萃取部分得到5个单体化合物和一个混合物,其结构鉴定为正二十二烷醇(Ⅰ),二十二烷酸(Ⅱ),蒲公英甾醇乙酸酯(Ⅲ),β-胡萝卜苷(Ⅳ),芹菜素(Ⅴ),β-谷甾醇(Ⅵ)和豆甾醇的混合物(Ⅶ)。结论所有化合物均为首次从该植物中得到。Objectlve To study the chemical constituents of Youngia japonica. Methods The constituents were isolated and purified by chromatography with silica gel column, then structurally identified by spectral analysis. Results We isolated five simple compounds and one mixture from the petroleum ether and acetoacetate extractions of ethanol extract, and its structures were identified as n-docosanol （Ⅰ ）, docosanoic acid （ Ⅱ ）, taraxasteryl acetate（Ⅲ ）, β-daucosterol（ Ⅳ ）, apigenin （ Ⅴ ）, β-sitosterol （ Ⅵ ） and stigmasterol（Ⅶ）. Conclusion All compounds are found in this plant for the first time.
