Morphological and phytochemical characterization of Lavandula dentata L. cultivated in Paraíba do Sul, Rio de Janeiro, Brazil

Lavandula dentata L., popularly known as lavender, is considered to be a medicinal plant that has great economic potential. The aims of the present study were characterize morphology L. grown in Paraíba do Sul, Rio de Janeiro, Brazil and determine content chemical composition its essential oil. Morphology was determined using optical microscope, digital calliper measuring tape. fresh material characteristics consisting branches, leaves, inflorescence described. oil obtained by hydrodistillation analyses performed gas chromatography (GC) coupled mass spectrometry (GC/MS). Our shows large number non-glandular trichomes identified, well two types glandular trichomes, including capitate peltate trichomes. This work achieved high which related vegetable biomass. major constituents found from monoterpenes: eucalyptol - 1.8 cineol (39.43%), camphor (20.11%), fenchone (18.40%). Thus, it possible dentata.
