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

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。

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 （1^H-NMR,13 ^C-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.
