Composición química de aceites esenciales de hojas de Fridericia florida DC. y Fridericia chica (Bonpl.)

This research project identifies the chemical composition of the essential oils extracted by steam distillation from fresh leaves of Fridericia florida DC L. G Lohman and Fridericia chica (Bonpl) (Bignoniaceae). The identification was performed by gas chromatography coupled to mass spectrometry (CG-EM). Then, the retention rates and mass spectra obtained were compared against the values reported by the literature. In this study, a yield of 0.033% was obtained, thus identifying 96.78% (Fridericia florida) and 91.95% (Fridericia chica) in its relative total composition. For Fridericia florida, 13 compounds were identified, with limonene being the major component (72.17%). For Fridericia chica, 11 compounds were identified, with germacrene D being the major component (63.77%). These results contribute to the phytochemistry of both species, identifying the volatile components in native species of traditional use. In addition, the study also contributes to the genus Fridericia, since no previous studies on essential oil composition have been reported.
