Chemical Characterization and Enantioselective Analysis of Tagetes filifolia Lag. Essential Oil and Crude Extract

Vladimir Morocho et al. Plants (Basel). .

Abstract

The essential oil (EO) of Tagetes filifolia Lag. was obtained from dried plant material through Clevenger-type steam distillation and analyzed using gas chromatography-mass spectrometry (GC/MS), a gas chromatography-flame ionization detector (GC/FID) and enantioselective gas chromatography. The results showed 50 compounds (93.33%) with a predominance of oxygenated monoterpenes. The main components were trans-anethole (55.57 ± 9.83%), tridecene <1-> (8.66 ± 0.01), methyl chavicol (5.81 ± 0.85%) and Neophytadiene (3.45 ± 0.88) Enantioselective analysis revealed linalool and <methyl-γ-> ionone as enantiomers. The identification of secondary metabolites from the ethyl acetate extract obtained by maceration was performed by GC-MS, NMR and by a literature comparison, determining the presence of mostly trans-anethole and a mixture of two triterpenes, fernenol and lupeol.

Keywords: Tagetes filifolia Lag.; anethole; essential oil.
