abstract A comparative study on the triterpenic acids composition of the outer barks of several Eucalyptus species (E. globulus, E. grandis, E. urograndis, E. maidenii and E. nitens) is reported. The contents of the main triterpenic acids identified in the five species varied between 4.5 g/kg in E. urograndis and 21.6 g/kg in E. nitens. It has been observed that, out of these Eucalyptus species outer barks, those from temperate and Mediterranean zones, namely E. Miens and E. globulus, are richer in triterpenic acids than the species from sub-tropical and tropical regions. Furthermore, E. globulus outer bark is clearly the richest in ursane acids, while E. Miens outer bark is the richest in oleanane and lupane acids.
