豆叶九里香的化学成分研究
利用开放的硅胶、ODS和Sephadex LH-20柱色谱及半制备型高效液相等色谱方法对豆叶九里香Murraya euchrestifolia中的化学成分进行分离纯化,结合理化性质和MS,NMR 等波谱学数据对化学结构进行解析.结果从豆叶九里香95％乙醇提取物的二氯甲烷部位共分离并鉴定了18个化合物,分别为sakuranetin(1),eriodictyol-7,4'-dimethyl ether(2),isosakuranetin(3),5-hydroxy-7,4'-dimethoxyflavanone(4),eriodictyol-7-methyl ether(5),lichexanthon(6),5,6,7-trimethoxycoumarin(7),5-hydroxy-6,8-dimethoxycoumarin(8),8-hydroxy-6-methoxy-3-n-pentylisocoumarin(9),ethyl caffeate(10),4-hydroxy-3,5-dimethoxycinnamic acid ethyl ester(11),methyl 3-(5'-hydroxyprenyl)-coumarate(12),(E)-coniferol(13),β-hydroxypropiovanillone(14),3-hydroxy-7,8-didehydro-β-ionone(15),3β-hydroxy-5α,6α-epoxy-7-megastigmen-9-one(16),grasshopper ketone(17),4-hydroxy-3,5-dimethoxybenzaldehyde(18),其中化合物1～15和18为首次从九里香属植物中分离得到,16和17为首次从该植物中分离得到.
