Identificação dos componentes do óleo essencial da espécie Eugenia ovalifolia Camb.

Abstract

The essential oil from a specimen of Eugenia ovalifolia Camb.family Myrtaceae (Tribo Myrteae ), extracted from the leaves on steam - distillation was analysed by Gas Chromatraphy coupled to Mass Spectrometry (GC-MS) using two columns of different polaritus. The components this oil now identificed though comparison with literature data of the Kovats indexes, retention times mass spectro from Wiley and NIST collections and also by the fragmentation analyses. The separation of the componentes by High Relation Gas Chromatograpy with Programed Temperature altared the identification of three different regions corresponding to the monoterpene, identifered. sesquiterpenes and oxygenated, hydrocarbon sesquiterpenes along with two major componends, globulol with Iower concentratrons and viridiflorol. So substances were were also. Biosynthetic proporals for the sesquiterpenes allowed the anelation of all identifed componentes
