title: [Studies on chemical constituents in fruit of Eucalyptus globulus].
abstract: OBJECTIVE
  AIM To study the chemical constituents of the fruit of Eucalyptus globulus.
  
  
  METHODS
  Various column chromatographies with silica gel were employed for the isolation and purification. The structures of the compounds were elucidated with of spectral analyses and chemical methods.
  
  
  RESULTS
  Five compounds were isolated and elucidated as follows: betulonic acid (I), betulinic acid (II), ursolic acid (III), corosolic acid (IV), daucosterol (V).
  
  
  CONCLUSIONS
  Compound I, II, III and IV were isolated from this plant for the first time.
