摘要
从裂叶荆芥花穗70%乙醇提取物中首次分得4种黄酮成分,经化学和光谱分析,分别确定为(Ⅰ)5,7-二羟基-4’,6-二甲氧基黄酮(5,-dihydroxy 1-4’,6-dimethoxyflavone,I);(Ⅱ)木犀草素-7-O-葡萄糖甙(Luteolin-7-O-glucose, Ⅱ);(Ⅲ) 3’羟基-4’,6,8-三甲氧基二氢黄酮-7-O-芸香糖甙(3’-hydroxyl-4’,6,8-trimethoxydi- hydroflavon-7-O-rutinose,Ⅲ);(Ⅳ)5-甲基-3’-羟基-4’,6-二甲氧基二氢黄酮-7-O-芸香糖甙(5-methyl-3′-hydroxyl-4′,6-dimethoxydihydroflavone-7-O-rutinose,Ⅳ)。
Four flavones were isolated from the 70% EtOH extract of spikes of Schizonepeta mulifida (L.) Briq. They were identified as 5, 7-dihydroxyl-4', 6-dimethoxyflavooe (I), Luteolin-7-Q-glucose (II), 3'-hydroxyl-4', 6, 8-trimethoxydi-hydroflavone-7-O-rutinose (III), 5-mithyl-3'-hydroxyl-4', 6-dimithoxydihydroflavone-7-O-rutinose( IV ). All of them were isolated for the first time from Scllizonepeta mulifida Briq.of Labiatae.
