蒲公英化学成分的研究

Chemical constituents of Taraxacum mongolicum

目的：对蒲公英（ＴａｒａｘａｃｕｍｍｏｎｇｏｌｉｃｕｍＨａｎｄ．Ｍａｚｚ．）的化学成分进行研究。方法：利用溶剂提取和硅胶柱层析进行分离，根据化合物理化性质和光谱数据鉴定其结构。结果：分离并鉴定５个化合物，分别为β谷甾醇、咖啡酸、绿原酸、槲皮素和木犀草素７Ｏ葡萄糖苷。结论：５个化合物均为首次从该种植物中分离得到。

OBJECTIVE: To investigate the chemical constituents of Taraxacum mongolicum. METHODS: Compounds were separated by rechromatography on silical gel, and their structures were deterimined by spectral analysis and chemical evidence. RESULTS: Five known compounds were elucidated as β sitosterol, caffeic acid, chlorogenic acid, quercetin, luteolin 7 O glucoside. CONCLUSION: All the compounds were isolated from this plant for the first time, chlorogenic acid was not isolated from Taraxacum genus previously.
