In vitro activity of the essential oil from Hesperozygis myrtoides on Rhipicephalus (Boophilus) microplus and Haemonchus contortus

ABSTRACT Commercial antiparasitics have been the main tool to control parasites, but due to the resistance development, plant extracts have been widely investigated to find new molecules. The present study aimed to investigate the in vitro acaricide and anthelmintic activities of the essential oil from the aerial parts of Hesperozygis myrtoides (A.St.-Hil. ex Benth.) Epling, Lamiaceae. The essential oil was obtained by hydrodistillation analyzed by GC-FID and GC-MS. Four tests were conducted in vitro to screen the antiparasitic action of the essential oil. The evaluation on Rhipicephalus (Boop...
