title: [Studies on chemical constituents in fruits of Eucalyptus globulus].
abstract: OBJECTIVE
  To study the chemical constituents in the fruits of Eucalyptus globulus Labill.
  
  
  METHODS
  The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by IR, NMR and MS evidences.
  
  
  RESULTS
  Fifteen compounds were obtained and identified as beta-sitosterol (1), betulinic acid (2), stigmasterol (3), euscaphic acid (4), 2a-Hydroxybetulinic acid (5), macrocarpal B (6), macrocarpal A (7), oleanolic acid (8), 3,4,3'-O-trimethylellagic acid (9), 3-O-methylellagic acid 4'-O-(2"-O-acetyl )-alpha-L-rhamnopyranoside (10), camaldulenside (cypellocarpin C, 11), 3-O-methylellagic acid 4'-O-alpha-L-rhamnopyranoside (12), 3-O-methylellagic acid (13), ellagic acid (14), and gallic acid (15).
  
  
  CONCLUSIONS
  Compounds 4 and 5 from genera Eucalyptus, 1, 3 and 11 from plant E. globulus, and 6, 7, 9 and 15 from the fruits of E. globulus were isolated for the first time.
