Chemical constituents of Ligularia dictyoneura

    摘要
  • 摘要: 目的研究网脉橐吾(Ligularia dictyoneura)的化学成分。方法应用色谱技术进行分离和纯化,MS,IR,NMR等波谱解析结构。结果从网脉橐吾中分离鉴定了4个倍半萜,分别签定为:ligudicin A (1), ligudicin C (2), ligudicin D (3)和isopetasin (4)。结论1为新化合物,2为新的天然产物,3和4为首次从网脉橐吾中分离得到。

     

    Abstract: AimTo study the chemical constituents of Ligularia dictyoneura. MethodsVarious chromatographic techniques were used to separate and purify the compounds. Their spectral data (MS, IR, NMR) were measured for structure elucidation. ResultsFour sesquiterpenes were isolated from Ligularia dictyoneura and their structures were identified as ligudicin A (1), ligudicin C (2), ligudicin D (3) and isopetasin (4). ConclusionCompound 1 is a new compound, compound 2 is a new natural product, and compounds 3 and 4 are obtained from Ligularia dictyoneura for the first time.
