红车轴草异黄酮化合物的分离鉴定

Isolation and Identification of Isoflavones from Trifolium pratense

对国产红车轴草 (TrifoliumpratenseL .)乙醇提取物的乙酸乙酯部分进行化学成分研究。采用溶剂处理和各种色谱方法从中分离得到了 8个异黄酮化合物 ,并利用波谱技术鉴定了结构。这 8个化合物分别为樱黄素、德鸢尾素、鹰嘴豆芽素A、芒柄花素、红车轴草素、染料木素。

To investigate the chemical constituents from the ethanolic extract of Trifolium pratense . Eight known compounds were isolated by using various column chromatographies and identified on the basis of spectral analysis. These compounds are prunetin (1), irilone (2), biochanin A (3), formononetin (4), pratensein (5), genistein (6), calycosin (7) and daidzein (8).
