对叶百部生物碱的结构研究

ALKALOIDS FROM THE ROOTS OF STEMONA TUBEROSA

    摘要
  • 摘要: 目的：分离鉴定对叶百部(Stemona tuberosa Lour)根部的生物碱成分。方法：用80～90%的乙醇提取,经硅胶柱色谱分离纯化,IR,MS,1H和13CNMR波谱方法确定化学结构。结果：分得4种生物碱成分,分别为对叶百部烯酮(tuberostemoenone)(I),对叶百部酮(tuberostemonone)(II),脱氢对叶百部碱(didehydrotuberostemonine)(III)和氧化对叶百部碱(oxotuberostemonine)(IV)。结论：化合物I为新化合物,化合物IV为首次从该植物中分得。

     

    Abstract: AIM: Isolation and structural identification of alkaloids from the roots of Stemona tuberosa Tour, collected in Hebei province, North China. METHODS: The crude alkaloids was extracted by using cold EtOH percolation. The structures were identified by IR, MS as well as various 2D NMR spectra including proton line broadening effect. RESULTS: Four alkaloids, namely tuberostemoenone (1), tuberostemonone (2), didehydrotuberostemonine (3) and oxotuberostemonine (4) were isolated. CONCLUSION: Tuberostemoenone is a new alkaloid with novel skeletone.
