Abstract Investigation of a new collection of Ageratum corymbosum resulted in the isolation of three new flavonoids, 4′-hydroxy-5,6,7,3′-tetramethoxyflavanone, 5-hydroxy-6,7,2′,3′,4′,5′-hexamethoxyflavone and 3′-hydroxy-5,6,7,2′,4′,5′-hexamethoxyflavone, named agecorynins E, F and G, respectively. Their structures were established by spectral methods and chemical transformations. 5-Hydroxy-7,8,2′,3′
摘要 对 Ageratum corymbosum 新藏品的研究导致分离出三种新的黄酮类化合物,4'-羟基-5,6,7,3'-四甲氧基黄烷酮,5-羟基-6,7,2',3',4' ,5'-六甲氧基黄酮和3'-羟基-5,6,7,2',4',5'-六甲氧基黄酮,分别命名为agecorynins E、F和G。它们的结构是通过光谱方法和化学转化建立的。5-Hydroxy-7,8,2',3',4',5'-六甲氧基黄酮(isoagecorynin F),从agehoustin B 获得,也有报道。
