目的:分离鉴定洋金花(Datura metel L.)中的化学成分。方法:采用硅胶柱色谱、ODS反相柱色谱等分离方法,对洋金花甲醇提取物进行分离纯化,分离得到了2个化合物,并通过理化性质及uv、NMR和MS等波谱学方法鉴定结构。结果:分离得到的2个化合物,分别是:Alkesterol B(1),睡茄素B(Lucium substance B,2)。结论:化合物1为首次从曼陀罗属植物中分离得到,化合物2为首次从该植物中分离得到。
Objective:To investigate the chemical constituents of Datura metel L.. Method:The chemical constituents were isolated by various isolation methods (silica gel, ODS) and their structures were elucidated by the analysis of spectral data ( UV, NMR and MS). Result : Two compounds were obtained and elucidated as following: Alkesterol B ( 1 ), Lucium substance B (2). Conclusion : Compound 1 and compound 2 are reported from the plants for the first time.
