Abstract
The present study determined the volatile chemical components of the essential oils (EA) of the Melinis minutifloraand Lantana camaraspecies, by means of gas chromatography coupled to a mass spectrometer, the species were collected in the cantons of Quilanga and Loja, the extraction was carried out by steam distillation. In the essential oil (EA) of M. minutiflora, 20 compounds were identified, representing 93.21%, the compounds in the highest concentration: 1-tetradecanol (16.30%), (E) -cariophylene (12.44%), germacrene D (10.99%), (E) -nerolidol (8.28%), δ-cadinene (5.61%), α-humulene (5.36%), viridiflorol (4.78%) and (Z) -β-farnesene (4.76%). In the AE of L. camara, 68 compounds were identified, representing 96.54%, the compounds with the highest concentration (E) -caryophyllene (15.46%), germacrene D (12.21%), α-humulene (9.92%), bicyclogermacrene (7.06%), γ-terpinene (5.97%) and germacrene B (4.66%). The species M. minutiflora and L. Camarahave repellent, acaricidal properties in adult larvae of Amblyomma cajennense and Rhipicephalus (Boophylus) microplus.
