Description
Summary:The chemical composition of the essential oils from leaves, stalks and inflorescences of Croton zehntneri obtained by hydrodistillation were analyzed by GC-MS and CG-FID. E-Anethole was the main component of the essential oils of all plant parts. Essential oils of leaves, stalks, inflorescences and E-anethole were tested at different concentrations against instar III larvae of Aedes aegypti and showed LC50 values of 56.2 ± 0.3, 51.3 ± 0.3, 57.5 ± 0.1 and 69.2 ± 0.5 μg/mL, respectively.
