title: [Chemical investingation of Chinese mangrove Sonneratia apetala II].
abstract: OBJECTIVE
  Isolation and structural elucidation of the constituents of China mangrove Sonneratia apetala.
  
  
  METHODS
  chromatography methods were used for isolation of compounds, spectroscopic methods were used for structural identifyication.
  
  
  RESULTS
  seven known compounds named (+/-) symgaresinol, betulinic acid, lupeol, lupeone, stigmast-5-ene-3beta, 7alpha-diol, beta-alpha myrin hexadecaneate, physcoion were isolated.
  
  
  CONCLUSIONS
  these known compouns were unreported previously from this plant.
