title: [Study on the alkaloids constituents from Voacanga africana].
abstract: OBJECTIVE
  To study the alkaloids of Voacanga africana.
  
  
  METHODS
  The alkaloids were isolated by normal phase silica gel and Sephadex LH-20 column chromatography. Their structures were elucidated by analysis of spectroscopic data.
  
  
  RESULTS
  Eight alkaloids were isolated and their structures were elucidated as voacangine(1), voacangine hydroxyindolenine(2), 19R-epi-voacristine(3), epi-ibogaine(4), vobasine(5), 19-epi-heyneanine(6), vobtusine(7) and voacamine(8).
  
  
  CONCLUSIONS
  Compounds 2-4 and 6 are isolated from this plant for the first time.
