胆木叶生物碱类成分研究

Alkaloids from the leaves of Nauclea officinalis

    摘要
  • 摘要:

    为了研究胆木叶中的化学成分, 采用硅胶、Sephadex LH-20、反相键合硅胶柱色谱等方法从胆木叶的95%乙醇提取物中分离得到8个生物碱类化合物, 并通过NMR、MS等波谱技术鉴定了化合物的结构, 分别为naucleactonin C (1)、strictosamide (2)、vincosamide (3)、pumiloside (4)、angustoline (5)、angustine (6)、18, 19- dihydroangustine (7) 和naucleofficine D (8)。化合物1为一新的吲哚类生物碱, 化合物6和7为首次从该植物中分离得到。

     

    Abstract:

    To study chemical constituents of the leaves of Nauclea officinalis, eight alkaloids were isolated from 95% ethanol extract by various chromatographic methods.  The structures were elucidated on the basis of spectroscopic data (IR, UV, ESI-MS, 1D and 2D NMR) and identified as naucleactonin C (1), strictosamide (2), vincosamide (3), pumiloside (4), angustoline (5), angustine (6), 18, 19-dihydroangustine (7) and naucleofficine D (8).  Compound 1 is a new indole alkaloid.  Compounds 6 and 7 were isolated from this plant for the first time.
