CAMUS, Juan A and TRUJILLO, Maritza A. CONTRIBUCIÓN A LA QUÍMICA DE LOS ACEITES ESENCIALES PROVENIENTES DEL OREGANO. Rev. Bol. Quim [online]. 2011, vol.28, n.1, pp.1-5. ISSN 0250-5460.
ABSTRACT It is very gratifying to use various classical techniques of the phytochemistry to isolation and identification of secondary metabolites providing from plants. Layer chromatography column chromatography fine preparative, liquid chromatography of high efficiency, together with the infrared spectroscopy and the ultraviolet-visible complement these techniques essential for the study of natural products. However, identification of compounds that this wonderful natural synthesis lab generously gives us, is only possible docking techniques NMR and the mass spectrometry, which allow to determine the molecular mass and functional groups, providing more refined information about the molecular structure of these complex products. Origanum vulgare (oregano) is a species accessible, economic and easy to obtain in our region. Using drag with vapour technique and extraction solvent (methanol-water and ethanol) essential oil is extracted and proceeded with column chromatography and thin layer to separate the active ingredients of essential oil. Then proceeded to perform analysis chromatographic and mass spectra in order to determine the main constituent present in the samples.
Keywords : Natural products; Origanum vulgare; essential oil.
