华夏鸢尾的化学成分研究

Chemical Constituents of Iris cathayensis Migo

目的:研究鸢尾科鸢尾属植物华夏鸢尾(IriscathayensisMigo)根茎中的化学成分。方法:采用70 %乙醇提取,硅胶柱层析分离及重结晶等方法从华夏鸢尾中分离其化学成分,通过波谱及化学方法进行结构鉴定。结果:分离并鉴定了9个化合物,其中3个为异黄酮类化合物,分别为:鸢尾苷元(tectorigenin ,Ⅰ)、德鸢尾苷元(irilone ,Ⅱ)、鸢尾苷(tectoridin ,Ⅴ) ;2个为二氢黄酮类化合物,分别为:5 ,2′二羟基 6 ,7 亚甲二氧基二氢黄酮(5 ,2′dihydroxy 6 ,7 methlenedioxyflavanone ,Ⅲ)、dihydroechioidinin(Ⅳ) ;1个为peltogynoids型化合物:irisoidsA(Ⅵ)。其余3个化合物分别为:十七烷酸(heptadecanoicacid ,Ⅶ)、胡萝卜苷(daucosterol,Ⅷ)和豆甾醇(stigmasterol,Ⅸ)。结论:这些化合物均为在该植物中首次分得,其中化合物Ⅳ为本属植物中首次发现。

AIM:To study the chemical constituents of Iris ca thayensis Migo.METHOD:Following extraction with 70% alcohol,the chem ical constituents of Iris cathayensis Migo were isolated by the silica gel c olumn chromatography and further purified by recystallization.RESULT: Nine compounds w ere isolated from Iris cathayensis, six of which are flavonoids.Based on th e physical properties and spectral data,six structures of them were identified a s tectorigenin(Ⅰ),irilone(Ⅱ),5,2′-dihydroxy-6, 7- meth lenedioxyflavanone(Ⅲ), dihydroechioidinin(Ⅳ), t ectoridin(Ⅴ)and irisoids A( Ⅵ).The others were elucidated as heptadecanoic acid(Ⅶ ),daucosterol(Ⅷ) and stigmasterol(Ⅸ).CONCLUSION:All of the nine co mpounds were iso lated from this plant for the first time,and compound Ⅳ was isola ted from Iris for the first time.
