Chemical Composition and larvicidal activity against Aedes aegypti of essential oils 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, -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
