The homoisoflavanone 5,7-dihydroxy-6-methoxy-3-(9-hydroxy-phenylmethyl)-chroman-4-one (1) and its structurally related 2',4',6'-trihydroxy-3'-methoxy-alpha-hydroxymethyl-beta-hydroxy-dihydrochalcone (2) along with the known pashanone (3), flavokawin B (4) and cardamonin or alpinetin chalcone (5) pinostrobin (6) and 5,8-dimethoxy-7-hydroxychroman-4-one (7) were isolated from dry leaves of Polygonum ferrugineum (Polygonaceae). To our knowledge, this is the first report of the isolation of a homoisoflavanone from the Polygonum genus and the Polygonaceae family, and could be an important chemotaxonomic finding. In addition, the pattern of substitution of this homoisoflavanone is different from others previously reported.
从铁角蓼（蓼科）的干燥叶片中分离出了高异黄酮5,7-二羟基-6-甲氧基-3-(9-羟基苯甲基)-色满-4-酮（1）及其结构相关的2',4',6'-三羟基-3'-甲氧基-α-羟甲基-β-羟基二氢查耳酮（2），以及已知的帕山酮（3）、黄茯芩B（4）和小豆蔻明或山姜素查耳酮（5）、松属素（6）和5,8-二甲氧基-7-羟基色满-4-酮（7）。据我们所知，这是首次从蓼属和蓼科中分离出高异黄酮的报道，可能是一项重要的化学分类学发现。此外，这种高异黄酮的取代模式与先前报道的其他高异黄酮不同。
