摘要
目的:分离和鉴定滇桂艾纳香的化学成分。方法:利用硅胶柱色谱、SephadexLH-20柱色谱等方法进行分离纯化,根据理化性质和波谱数据进行结构鉴定。结果:得到6个黄酮类化合物,分别鉴定为:圣草素-7,4′-二甲醚(1),圣草素-7,3′-二甲醚(2),圣草素-7-甲醚(3),槲皮素-7,3′,4′-三甲醚(4),柽柳素(5),鼠李柠檬素(6)。结论:化合物1～6均为首次从该种植物中分离并鉴定。
Objective： To separate and identify the chemical constituents of Blumea riparia. Method： The compounds were separated and purified by repeated silica gel, Sephadex LH - 20 column chromatographiy. The structures of these compounds isolated were identified by analysis of their spectral data, physical and chemical properties. Result： Six flavonoids were isolated from B. r/par- /a. and their structures were identified as eriodictyol-7, 4＇-dimethyl ether （1）, eriodictyol-7, 3＇-dimethyl ether （2）, eriodictyol-7- methyl ether （3）., quereetin-7, 3＇, 4＇-trimethyl ether （4）, tamarixetin （5）, rhamnocitrin （6）. Condusion： Compound 1-6 were obtained from B. riparia, for the first time.
