title: Effectiveness of Asteraceae extracts on Trichostrongylidae eggs development in sheep.
abstract: Data on in vitro evaluation of extracts of three species of the Asteraceae family on the development of Trichostrongylidae eggs in sheep are presented. Egg hatchability was tested using herbal extracts prepared in a Soxhlet extractor, and using hydrolate prepared by means of hydrodistillation. The laboratory tests showed that the ethanol extract from flowers of the species Aster lanceolatus presented high activity against Trichostrongylidae eggs development in sheep, inhibiting larva formation by 91% within 48 hours, and maintaining similar rates after 72 hours.
