摘　　要：从甘肃庆阳产中草药乌蓼中首次分离得到了５个黄酮类化合物：５７二羟基６７二甲氧基黄酮（１），５７二羟基黄酮（２），５７二甲氧基４′羟基黄酮（３），桑色素７ＯβＤ葡萄糖甙（４），５羟基３′甲氧基双氢黄酮７Ｏ芸香糖甙（５）．Five flavone compounds were isolated from the alcohoic extract of the whole plant of Polygomum aviculare L.Structure of them were elucidated by spectroscopic and chemical evidence as follows:57 dihydroxy 6 methoxyflavane(1);57 dihydroxy flavane(2);57 dimethoxy 4′ hydroxyflavane(3);morin 7 O β D glucoside(4);and 5 hydroxy 3′ methoxyflavanone 7 O rutinoside(5).They were isolated from Polygomum aviculare L.for the first time.
