title: [Compounds from marine mangrove plant Bruguiera sexangula var. rhynchopetala].
abstract: OBJECTIVE
  To investigate the chemical constituents in Bruguiera sexangula var. rhynchopetala.
  
  
  METHODS
  Silica gel flash chromatography together with Sephadex LH - 20 were performed for the isolation and purification of the petrol ether fraction of this plant, and the structures were elucidated by spectral analysis as well as the comparison of the spectral data with those reported in the literatures.
  
  
  RESULTS
  Nine compounds were obtained and identified as lupeol (1), lupeone (2), trans-hydroxy-cinnamoyl ester of lupeol (3), taraxerone (4), beta-amyril-palmitate (5), squalene (6),beta-sitosterol (7), daucosterol (8) and 7alpha-hydroxy-sitosterol (9).
  
  
  CONCLUSIONS
  All the compounds were first isolated from B. sexangula var. rhynchopetala.
