Análisis químico y enantiomérico de la fracción volátil destilada de la especie Ecuatoriana Dalea mutisii (Kunth)

Abstract

Abstract:Through this research, the chemical and enantiomeric composition of the essential oil of Dalea mutisii, obtained by steam distillation distillation, was determined, determining its physical properties as relative density and refractive index. The qualitative (CG-MS) and quantitative (CG-FID) chemical composition was also analyzed. Likewise, an enantiomeric analysis was performed through CG (enantioselective column). In addition, a sensory characterization of the odor was carried out using GC-O using the AEDA dilution technique. Sixty-three compounds were characterized and quantified, using the method of true quantification by calibration and use of the internal standard, α-pinene (46.47%), β-pinene (16.03%), β-Felandrene (13) were identified as major compounds. , 23%), Mirceno (6.87%) and (Z) -β-ocimene (5.44%), whose results do not differ much when compared with that obtained by the calculation method of the relative response factor according to enthalpy. of combustion. The enantiomeric analysis revealed the presence of enantiomeric relationships of 6 components (α-pinene, β-pinene, α-phellandrene, β-phenlandrene, α-Cubebene and trans-Muurola-4 (14), 5-diene). In the sensory analysis, α- and β-pinene, α-phellandrene and (Z) -β-Ocimeno were identified, exhibiting the characteristic woody, herbaceous and sweet smells, respectively.
