Abstract: Gastrointestinal parasites cause economic losses to the cattle production, in Brazil and worldwide, mainly caused by Bunostumom sp., Cooperia sp. and Trichostrongylus sp. The aim of this study was to determine the in vitro efficacy of hydroalcoholic extract of Artemisia annua (H. 7) against these parasites. The H. 7 was produced after 7 days of storage at 4 degrees C and then lyophilized. With this herbal the egg hatch test (EHT) and larval migration inhibition (LMI) were performed, in six replicates with different concentrations (0.78 to 50mg/mL). To analyze the chemistry composition the complete phytochemical screening was done. In EHT efficiency ranged from 94.08 +/- 2.58% at the highest concentration to 15.67 +/- 0.97% in the lowest concentration. In LMI test the values ranged from 90.05 +/- 0.55% to 4.12 +/- 0.46%. Phytochemical tests showed many chemical compounds with anthelmintic properties. The results obtained in biochemical tests together with those found in in vitro tests showed that the extract produced has the potential to combat intestinal nematodes of cattle. Further studies should be conducted to maximize the effectiveness of H. 7 and other extractions from A. annua, because it demonstrated excellent results in both experiments.
