I. SAMFIRA, S. RODINO, P. PETRACHE, R. T. CRISTINA, M. BUTU, M. BUTNARIU. CHARACTERIZATION AND IDENTITY CONFIRMATION OF ESSENTIAL OILS BY MID INFRARED ABSORPTION SPECTROPHOTOMETRY. Digest Journal of Nanomaterials and Biostructures, 10, pp. 557-566, 2015.

Abstract: Characterization and confirmation of identity as part of the structural interaction perspective of essential oils biostructure from lavender (Lavandula officinalis), peppermint
(Mentha piperita), green Douglas (Pseudotsuga menziesii), fir (Abies alba) and chicory (Cichorium intybus) has been addressed by qualitative detection and quantification of specific natural clusters, by infrared absorption spectrophotometry. The method allows the identification of structural components that are characteristic to essential oils, due to steric and electronic effects of vibrational coupling (neighbouring bonds acting on force constant of the bond, changing the position of the absorption band). Through this research the essential oil identity was confirmed by quantifying the structural components and by assigning characteristic absorption bands in the spectrum measured. Comparisons of spectra by calculating the correlation coefficient is a convenient, fast and secure method for objective confirmation of essential oils identity.

Keywords: Essential oils, Absorption spectrophotometry, Correlation coefficient
