马蔺根的化学成分研究

Chemical Constituents in the Roots of Iris lactea Pall.var.Chinensis

从鸢尾科植物马蔺根70%乙醇提取液中分离鉴定了11个已知化合物,分别为:5,7,3′-三羟基-4′-甲氧基黄酮(5,7,3'-Trihydroxy-4'-methoxyflavone,1),3、6、7-四羟基口山酮-2-C-β-D-葡萄糖(mangiferin,2),5-羟基-7,4'-二甲氧基黄酮-6-C-β-D-葡萄糖-2-O-L-鼠李糖(embinin,3),1-β-D-arabinofuranosyluracil(4),hyperolactoneB(5),香草酸(6),2-methyl-propyl-β-D-glucopyranoside(7),decanoic acid(8),4-methylpentanoic acid(9),胡萝卜苷(10),β-谷甾醇(11)。其中化合物1、4、5、7、8、9为首次从该植物中分离得到。

The roots of Iris lactea Pall.var.Chinensis（Fisch.） koidz.belonging to Irdaceae were extracted with 70% alcohol.Eleven compounds were isolated and identified as 5,7,3＇-trihydroxy -4＇-methoxyflavone（1）,mangiferin（2）,embinin（3）,1-β-D-arabinofuranosyluracil（4）,hyperolactone B（5）,vanillic acid（6）,2-methylpropyl-β-D-glucopyranoside（7）,decanoic acid（8）,4-methylpentanoic acid（9）,daucosterol（10）,and β-sitosterol（11）.Compound 1,4,5,7,8,9 were isolated from this plant for the first time.
