Atividade fungitóxica in vitro dos óleos essenciais de Lippia sidoides Cham., Cymbopogon citratus(D.C.) Stapf. e de seus constituintes majoritários no controle de Rhizoctonia solani e Sclerotium rolfsii

Abstract: RESUMO O objetivo deste estudo foi avaliar o potencial fungitóxicos dos óleos essenciais de Cymbopogon citratus, Lippia sidoides, e de seus constituintes majoritários, sobre o crescimento micelial dos fitopatógenos Rhizoctonia solani e Sclerotium rolfsii. A caracterização química do óleo de L. sidoides demonstrou a presença do carvacrol (33,27%) e o 1,8-cineol (24,41%) como seus componentes majoritários. Enquanto que o citral (77,6%) foi o constituinte majoritário do óleo essencial de C. citratus. A avaliação … Show more

“…Sacchetti et al (2005) [28] reported the presence of 65 to 86% citral in the EO of this species. In more recent studies, Lucena et al (2015) [29] found levels of neral 43.69% and 34.05% geranial, and Gonçalves et al (2015) [9] reported the presence of geranial (46.32%) and neral (31.28%) values similar to those found in OE C. citratus analysis in this study.…”

“…Popular medicine uses its tea or muffled, prepared from its leaves such as soothing, analgesic, antipyretic, antirheumatic, diuretic and digestive disorders. Through studies it is possible to attribute antimicrobial activity to the geranial and neral major compounds present in their EO [9].…”

“…Elevated levels of Geranial and Neral in the chemical composition of lemongrass were observed by [22], with a mean of approximately 51% and 36%, respectively. The authors [23] also observed similar percentages for Geranial (46.3%) and Neral (31.28%). Yet [24] found levels of 43.6% for Neral and 34% for Geranial, values that are different to the ones found on this work, where the highest percentage was of Neral.…”

“…The antifungal activity of citral, the major constituent of the essential oil of C. citratus, may cause rupture of the cell membrane integrity and extravasation of the cellular components of the microorganisms. In the present study, it was found that this constituent in particular was more effective than the essential oil itself, with absence of the mycelial growth of R. solani and S. rolfsii [21,22].…”
