洋金花的化学成分研究(Ⅴ)

Chemical Constituents from Datura Metel L.(V)

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.
