Resumo

The volatile composition of the essential oils from leaves and roots of Eupatorium betonicaeforme (D.C.) Baker was analyzed by GC−MS. A total of 12 compounds were identified. β-Caryophyllene (12.4−41.7%), α-humulene (11.7−14.6%), γ-muurolene (10.4−19.0%), bicyclogermacrene (15.0−17.5%), 2,2-dimethyl-6-vinylchroman-4-one (10.3−25.5%), and 2-senecioyl-4-vinylphenol (8.5−41.0%) were the most prominent constituents. The former two compounds were isolated and characterized by spectroscopic data. The essential oils and the isolated compounds were tested against Aedes aegypti larvae survival. The results obtained show that the essential oil from roots and 2,2-dimethyl-6-vinylchroman-4-one (10.3−25.5%) could be considered as natural larvicidal agents. Keywords: Eupatorium betonicaeforme; essential oil; Aedes aegypti; larvicidal activity; 2,2-dimethyl-6-vinylchroman-4-one
