白鲜皮的化学成分研究

目的:研究白鲜Dictamnus dasycarpus干燥根皮的化学成分。方法:采用硅胶柱色谱、制备薄层色谱、Sephadex LH-20等方法分离,应用波谱方法鉴定其结构。结果:从白鲜皮中分离得到12个化合物,分别为白鲜碱(dictamnine,Ⅰ),酮(fraxinellone,Ⅱ),茵芋碱(skimmianine,Ⅲ),γ-崖椒碱(γ-fagarine,Ⅳ),β-谷甾醇(-βsitosterol,Ⅴ),黄柏酮(obacunone,Ⅵ),柠檬苦素地噢酚(limonin disophenol,Ⅶ),fraxinellonone(Ⅷ),汉黄芩素(wogonin,Ⅸ),如忒文(rutevin,Ⅹ),kihadinin B(Ⅺ),dasycarine(Ⅻ)。结论:化合物Ⅸ,Ⅺ为首次从该属植物中分离得到,化合物Ⅷ为首次从本植物中分离得到。

Studies on chemical constituents in bark of Dictamnus dasycarpus

OBJECTIVE: To study the chemical constituents in bark of Dictamnus dasycarpus. METHOD: Isolation and purification were carried out on silica gel column chromatography, prepared thin layer chromatography and sephadex LH - 20, et al. The structures were identified by spectral analysis. RESULT: Twelve compounds were obtained from bark of D. dasycarpus and the structures were determined as dictamnine (I), fraxinellone (II), skimmianine (III), gamma-fagarine (IV ), beta-sitosterol (V), obacunone (VI), limonin disophenol (VII), fraxinellonone (VIII), wogonin (IX), rutevin (X), kihadinin B (XI), dasycarine (XII). CONCLUSION: Compounds IX and XI were isolated from genus Dictamnus for the first time, and compound VIII was isolated from the species for the first time.
