Abstract Besides agecorynin C, eupalestin and lucidin dimethyl ether, two new highly oxygenated flavones were isolated from Ageratum houstonianum . Their structures were established by spectroscopic and degradative evidence as 5, 6, 7, 8, 2′, 3′, 4′, 5′-octamethoxyflavone and 5, 6, 7, 2′, 3′, 4′, 5′-heptamethoxyflavone.
摘要 除了agecorynin C、eupalestin 和lucidin 二甲醚外,还从Ageratum houstonianum 中分离到了两种新的高氧化黄酮。它们的结构通过光谱和降解证据确定为 5, 6, 7, 8, 2', 3', 4', 5'-八甲氧基黄酮和 5, 6, 7, 2', 3', 4', 5'-七甲氧基黄酮。
