红波罗花醋酸乙酯部位化学成分研究

Chemical constituents from acetyl acetate extract fraction of Incarvillea delavayi

目的：对紫葳科Bignoniaceae角蒿属植物红波罗花Incarvillea delavayi的化学成分进行分离纯化和结构鉴定。方法：采用硅胶、Sephadex LH-20柱色谱和制备型高效液相色谱方法进行分离 应用NMR和MS等波谱方法鉴定化合物结构。结果：从红波罗花醋酸乙酯部位中分离得到7个化合物,结构分别鉴定为leucoseceptoside A（1）,角胡麻苷（2）,棘木苷（3）,edgeworthin（4）,1,2,4-三甲氧基苯（5）,原儿茶酸（6）,异香草醛（7）。结论：化合物3,4为首次从该属植物中分离得到,化合物1~2,5~7为首次从该植物中分离得到。

Objective： To investigate chemical constituents from acetyl acetate extract fraction of Incarvillea delavayi. Meth- od： The chemical constituents were isolated by chromatographic techniques with silica gel, Sephadex LH-20 and semipreparative HPLC. The structures of those compounds were identified by NMR and MS, Result： Seven compounds were isolated from the EtOAC extract of L delavayi and their structures were identified as leucoseceptoside A （ 1）, martynoside （ 2）, cornoside （ 3）, edgeworthin （4）, 1,2,4-trimethoxybenzene （5）, protocatechuic acid （6） and 3-hydroxy-p-anisaldehyde （7）, respectively. Compounds 1-2 were phenylpropanoid glycosides. Conclusion： Compounds 3, 4 were obtained from the genus lncarvillea for the first time. Compounds 1-2, 5-7 were first isolated from this plant.
