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。 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.
