Studies on chemical constituents in roots of Codonopsis convolvulacea Kurz

目的 :研究鸡蛋参的化学成分。方法 :溶剂提取 ,硅胶柱色谱分离 ,根据化合物理化性质和光谱数据鉴定其结构。结果 :分离得到 5个化合物 ,为蒲公英萜酮 (taraxerone) ( 1) ,蒲公英萜醇 (taraxerol) ( 2 ) ,莽草酸(shikimicacid) ( 3 ) ,丁香脂素 (syringaresinol) ( 4 ) ,豆甾醇 (stigmasterol) ( 5)。 结论

OBJECTIVE:To Study the chemical constituents in the roots of Codonopsis convolvulacea. METHODS:Chromatography and spectral analysis were used to isolation the constituents and elucidate their structures.RESULTS:Five compounds were isolated from the alcohol extracts of the roots and identified as taraxerone(1), taraxerol(2), shikimic acid(3), syringaresinol (4),stigmasterol(5).CONCLUSION:All the compounds are isolated from the roots of this plant for the first time.
