Abstract: A new flavone glycoside, 5-hydroxy-6,7,4-trimethoxyflavone-8-O-β-D-glucoside(1), together with six known flavonoids, genkwanin (2), cirsimartin(3), pedalin(4), ladanetin(5), isothymusin-8-O-β-D-glucoside(6),and isoquercitri (7),was isolated from the aerial parts of Isodon enanderianus(Labiatae). Their stuctures were elucidated on the basis of spectroscopic evidence.

Key words: Labiatae

摘要： 从紫毛香茶菜(Isodon enanderianus)的茎叶提取物中分离到7个黄酮类化合物,经波谱分析鉴定,其中一个为新的黄酮甙,即5-羟基-6,7,4＇-三甲氧基黄酮-8-O-β-D-葡萄糖甙 (1);其它6个已知的黄酮类化合物分别为芫花素(genkwanin,2)、滨蓟素(cirsimartin,3)、胡麻素(pedalitin,4)、鼬瓣花亭(ladanetin,5)、isothymusin-8-O-β-D-glucoside (6)和槲皮甙(quercitrin,7).
