Resumen:
>Some Eucalyptus species produce oils with biological activities and the effect of theirinterspecific hybridization on the enantiomeric composition of terpenes has not been reported. Theenantiomeric excesses of monoterpenes in the essential oil of Eucalyptus grandis × E. tereticornisand its parental taxa were determined by gas chromatography-mass spectrometry (GC-MS), andto resolve coelutions problems by preparative high performance liquid chromatography (HPLC)and GC-MS with two columns in series. The essential oil composition of the hybrid presentedqualitative and quantitative differences with the composition of its parental taxa. Great differenceswere found for the enantiomeric ratio in monoterpene alcohols among the three essential oils. Ourresults suggest that the enantiomeric analysis can be a reliable method for the study of how theinterspecific hybridization can module the enantiomeric chemical profile in Eucalyptus essentialoils. These results suggest the use of interspecific hybridization to improve or expand the sourceof bioactive compounds.
