三脉紫菀化学成分的研究

摘要

目的：研究三脉紫菀的化学成分。方法：应用正、反相硅胶柱色谱法进行分离纯化,根据理化性质和波谱数据鉴定化合物结构。结果：从三脉紫菀甲醇提取物中分离得到了5个化合物,分别鉴定为：β-谷甾醇（1）、柚皮素（2）、木栓酮（3）、表木栓醇（4）、3＇,4＇,5,7-四羟基双氢黄酮（5）。结论：化合物2-5为首次从该植物中分离得到。%Objective： To study the constituents of the whole plant of O.Falcata Bunge.Method： The chemical constituents were isolated by the column chromatography of silica gel and RP-18 gel.Their chemical structures were elucidated on the basis of physicochemical properties and spectral data analisis.Result： 5 compounds were obtained and identified as β-sitosterol（1）naringenin（2）5,6-dihydroxy-2,7,3′,4′-tetramethoxyflavonol（3）、5,6-dihydroxy-2,7,4′-trmiethoxyflavonol（4）3′,4′,5,7-tretahydroxy-flavanone（5）Conclusion： Compounds 2-6 were isolated from the plant for the first time.
