| Popis: | In this study, effects of different extraction methods, namely microwave-assisted hydrodistillation (MAHD) and solvent-free microwave extraction (SFME) were investigated in comparison with that of conventional hydrodistillation (HD) in terms of yield, active components, and antimicrobial activities (4 Gram-positive bacteria and 4 Gram-negative bacteria) of lemon verbena leaves essential oils (EOs). Gas chromatography/ mass spectrometry results indicated that geranial (25.54-28.53 %), neral (20.76-23.51 %), and limonene (11.21-12.51 %) were main active components of lemon verbena EOs. There were significant differences among active components of EO obtained by SFME method with those of HD and MAHD methods (P |
