摘要
目的:研究显苞芒毛苣苔地上部分乙酸乙酯部位的化学成分。方法:利用硅胶色谱柱层析进行分离纯化,通过波谱数据结合理化性质鉴定结构。结果:从显苞芒毛苣苔的乙酸乙酯部位中分离鉴定了8个化合物,分别为:koaburaside(1)、松柏醛(2)、丁香醛(3)、反-3,5-二甲氧基-4-羟基肉桂醛(4)、2,4'-二羟基苯乙酮(5)、对羟基苯乙酮(6)、β-胡萝卜苷(7)、β-谷甾醇(8)。结论:其中,化合物1、2为首次从该属植物中分离得到。
Objective：To study the constituents of EtOAc extract from Aeschynanthus bracteatus.Methods：The constituents were isolated and purified by chromatography on silica gel and the structures of the compounds were determined by MS and NMR spectral analysis.Results：On the basis of spectroscopic analysis and comparison with the reported data,compounds were identified as koaburaside（1）,coniferaldehyde（2）,syringaldehyde（3）,sinapinaldehyde（4）,2,4′-dihydroxyacetophenone（5）,piceol（6）,β-daucosterol（7）,β-sitosterol（8）.Conclusion：Compounds 1 and 2 are obtained from this genus for the first time.
