Chemical composition and larvicidal activity against Aedes aegypti of essential oil from Croton jacobinenesis Baill.

Resumen / abstract: 

Composición química y actividad larvicida contra Aedes aegypti de los aceites esenciales de Croton jacobinenesis Baill.

La composición química de los aceites esenciales de las hojas, los tallos y las inflorescencias de Croton jacobinensis obtenidos por hidrodestilación se analizaron mediante GC-MS. E-cariofileno, α-pineno, 1,8-cineol, viridifloreno, 8-cadineno fueron los principales componentes de los aceites esenciales de partes de la planta. Los aceites esenciales de las hojas, tallos e inflorescencias fueron probados en diferentes concentraciones en contra de instar III de las larvas de Aedes aegypti y mostraron LC50 de 79,3; 117,2; 65,8 μg/ml, respectively.

 

Chemical composition and larvicidal activity against Aedes aegypti of essential oil from Croton jacobinenesis Baill.

The chemical composition of essential oils from leaves, stalks and inflorescences of Croton jacobinensis obtained by hydrodistillation were analyzed by GC-MS. E-caryophyllene, 1,8-cineole, α-pinene, viridiflorene, 8-cadinene were the main components in essential oils from plant parts. Essential oils of leaves, stalks, and inflorescences were tested at different concentrations against instar III larvae of Aedes aegypti and showed LC50 of 79.3, 117.2, 65.8 μg/ml, respectively.

Keywords: Croton jacobinensis, essential oil, Aedes aegypti, larvicidal activity.
