| 摘 要： | 用硅胶、反相硅胶、凝胶和薄层色谱等方法从折苞斑鸠菊(Vernonia spirei Gandog)甲醇提取物的乙酸乙酯部分中分离黄酮类成分,得到2个化合物,通过光谱和波谱分析,分别鉴定为:5,7,4’-三羟基-6,3-二甲氧基黄酮(Ⅰ)、5,7,4’-三羟基-6,3-二甲氧基黄酮(Ⅱ)。以上化合物均为首次从该植物中分离得到。

| Abstract: | The chemical constituents of Vernonia spirei Gandog were studied.The constituents were separated and purified from MeOH extract of the whole plant with column chromatographic methods through silica gel,RP-18 silica gel,Sephadex LH-20,HPLC,and preparative TLC.Their chemical structures were characterized by spectroscopic methods including NMR and EIMS.The result showed that Vernonia spirei Gandog contained two components including 5,7,4'-trihydroxy-6,3'-dimethoxyflavone(Ⅰ),5,3'-dihydroxy-6,7,4'-trimethoxyflavone(Ⅱ).These compounds were obtained from this genus for the first time. |
