Chemical composition and evaluation of antioxidant activity of leaf essential oil Eucalyptus camaldulensis from Norte de Santander (Colombia)
The essential leaf oil (AE) of the species Eucalyptus camaldulensis collected in the department of Norte de Santander (Colombia), was studied in order to characterize its chemical composition and determine their antioxidant activity. The extraction of AE was performed by steam, and the identification of the main components are made by Gas Chromatography High Resolution coupled to mass spectrometry to determine the chemical composition variability in climatic conditions given that the region presents. The AE has mixtures of mono-and sesquiterpenes, being 1,8-cineole the component with the highest concentration with 81.0%, followed by α-pinene with 5.26%. Entrapment capacity ABTS radical cation and radical DPPH+ to determine the antioxidant activity of the AE two methods were used. Percent inhibition (% Inh) with DPPH radical methodology did not exceed 10% in trials against radical ABTS+ was observed that only reaches sufficient values to very high concentrations (>250ppm)
