窄萼凤仙花化学成分的研究

Chemical Constituents from Impatiens stenosepala

首次从窄萼凤仙花(Impatiens stenosepala Pritz.ex Diels)中分离得到九个化合物,通过波谱学方法分别鉴定为槲皮素(1)、山柰酚(2)、阿魏酸(3)、对羟基苯甲酸(4)、4'-OH黄芩素(5)、洋芹素(6)、2,5,7,8-四羟基萘醌(7)、5,8-二羟基萘醌(8)及东莨菪素(9)。

Nine compounds were isolated from Impatiens stenosepala for the first time.Their structures were determined by spectroscopic method as quercetin（1）,kaempferol（2）,ferulic acid （3）,p-hydroxybenzoic acid（4）,4′-hydroxyscutellarin（5）,apigenin（6）,2,5,7,8-tetrahydroxy naphthoquinone（7）,5,8-dihydroxy naphthoquinone（8）,and scopoletin（9）.
