两头毛乙酸乙酯部位化学成分研究

Studies on Chemical Constituents of Ethyl Acetate Portion of Incarvillea arguta

摘要:

目的: 研究两头毛中乙酸乙酯部位的化学成分。 方法: 采用硅胶柱色谱、HP-20和Sephadex LH-20等分离手段对乙酸乙酯萃取部分进行分离纯化, 通过波谱数据分析(¹H-NMR,¹³C-NMR)进行结构鉴定。 结果: 从乙酸乙酯萃取部分分离5个化合物,分别鉴定为suberosenol A( 1 ),suberosenol B( 2 ),suberosenone( 3 ),山奈酚-7-O-α-L-鼠李糖苷( 4 ),阿魏酸( 5 )。 结论: 上述化合物均为首次从该植物中分离得到。

Abstract:

Objective:To study the chemical constituents of the ethyl acetate portion of Incarvillea arguta. Method: The ethyl acetate portion were isolated and pured by silica gel column chromatography, HP-20 and Sephadex LH-20.Their chemical structures were elucidated by spectral data(¹H-NMR,¹³C-NMR). Result: Five compounds were isolated from the ethyl acetate portion. They were identified as suberosenol A( 1 ),suberosenol B( 2 ),suberosenone( 3 ),kaempferol-7-O-α-L-rha mnoside( 4 ),ferulic acid( 5 ). Conclusion: All compounds were isolated from this plant for the first time.
