 Six essential oils obtained of Colombian species were analyzed by Fourier transform ion cyclotron resonance mass spectrometry coupled to negative electrospray ionization (ESI(-)/FT-ICR-MS), technique offered a selective ionization of non-basic nitrogen compounds and acid compounds1. Only deprotonated molecular ions or molecular ion adducts (Na+ or Cl-) are observed in the mass spectrum the results (figure 1) showed that the main classes were detected in the most bio-oils (classes with a percentage higher than 1, in relative abundance), but each class presents a different distribution and compounds. Have been identified between 1100-3600 compounds in the samples studied that present between 1-36 atoms of carbon. The most dominant classes were the oxygen compounds O4, O2, and O3. Found different and unique compounds in each bio-oil.
