Chemical constituents and larvicide potential against Aedes aegypti of the esse...
Pereira, Ana Patrícia Matos; Martins, Thércia Gabrielle Teixeira; Araújo Neto, Ari Pereira de; Conceição , Carlos Eduardo PereiraEssential oils extracted from medicinal plants have been shown to be an alternative in the search for natural larvicides. Thus, the present study aimed to evaluate the larvicidal activity of essential oil extracted from the leaves of Origanum vulgare L. leaves. The essential oil was extracted by hydrodistillation at 100°C for 3 h, with chemical characterization through Gas Chromatography coupled to mass spectro...

Pereira, Ana Patrícia Matos; Martins, Thércia Gabrielle Teixeira; Arruda, Mariana Oliveira; Dias, Andressa Almeida SantanaThis study aimed to determine the chemical constituents and larvicidal activity of the essential oil of Plectranthus amboinicus (Lour.) Spreng against larvae of the Aedes aegypti mosquito. The essential oil (EO) was extracted by hydrodistillation at 100 ° C for 3 hours. The chemical composition was obtained by Gas Chromatography coupled to Mass Spectrometry (GC / MS). To assess larvicidal activity, Aedes aegypt...
