Abstract Four new flavonoids, three flavanones and one chalcone, were isolated from aerial parts of Ageratum strictum. Their structures were establised as 3′6′-dihydroxy-2′, 4′-dimethoxy- 3, 4-methylenedioxy-chalcone, 6-hydroxy-5,7-dimethoxy-3′,4′-methylenedioxyflavanone, 6-hydroxy- 5,7,3′,4′-tetramethoxyflavanone and 6,4′-dihydroxy-5,7,3′-trimethoxyflavanone on the basis of spectral data and chemical
摘要 从Ageratum strictum 地上部分分离得到4 种新的黄酮类化合物,3 种黄烷酮和1 种查耳酮。它们的结构被确定为 3'6'-二羟基-2', 4'-二甲氧基-3, 4-亚甲二氧基-查尔酮, 6-羟基-5,7-二甲氧基-3',4'-亚甲二氧基黄烷酮, 6-羟基-基于光谱数据和化学降解的 5,7,3',4'-四甲氧基黄烷酮和 6,4'-二羟基-5,7,3'-三甲氧基黄烷酮。
