Resumo: | ABSTRACT: Fasciolosis has been diagnosed in cattle, goats, sheep and horses in southern and southeastern Brazil. Effective alternative treatments are the targets of study. One promising alternative is the use of plant extracts. The aim of this study was to perform phytochemical analysis of extracts of Eugenia uniflora L., Harpagophytum procumbens, Psidium guajava L. and Stryphnodendron adstringens, and to evaluate the in vitro efficacy of these extracts on ovicidal activity in Fasciola hepatica. Plant extracts were analyzed for phytochemical properties. F. hepatica eggs were collected directly from the gallbladders of animals diagnosed as positive for fasciolosis on post mortem examination. One hundred eggs were incubated with 3 ml of each extract at concentrations of 0.10%, 0.25% and 0.50%, albendazole 0.50% (positive control) or tap water (negative control). To determine anti larval efficacy of each plant extract, hatched eggs were counted and the averages were used. Phytochemical analysis revealed the presence of phenolic compounds, tannins and terpenes in most extracts. E. uniflora L. extract was 100% effective at 0.10%, H. procumbens was effective at 0.25% and P. guajava L. and S. adstringens extracts were 100% effective at all concentrations tested. Taken together, the data suggested that ovicidal activity in F. hepatica is due to the presence of these bioactive compounds.
