title: [Isolation and identification of brominated alkaloids from the sponge Ircinia sp].
abstract: OBJECTIVE
  To study the alkaloids from sponge Ircinia sp..
  
  
  METHODS
  The alkaloids were isolated and purified by various chromatographic techniques, and their structures were elucidated by physicochemical and spectral data.
  
  
  RESULTS
  Five alkaloids were isolated and identified as fistularin-1 (1), fistularin-3 (2), aerothionin (3), 11 -hydroxyaerothionin (4), suberamolline A (5).
  
  
  CONCLUSIONS
  All the alkaloids are isolated from Ircinia sp. for the first time.
