Abstract: Research towards plant compounds with activity against worm parasites has been carried out for a number of decades; however it is especially important now when drench resistance has compromised the effectiveness of present control methods. In this study we characterized the composition of Mentha piperita essential oil and evaluated its anthelmintic effect against developmental stages of trichostrongylids from naturally infected goats (95% Haemonchus contortus and 5% Trichostrogylus spp.) through the egg hatch and larval development assays. The major constituent of the tested substance quantified by gas chromatography was menthol (58.35%). The lowest concentration of essential oil with 100% efficacy in all in vitro tests against caprine trichostrongylids was 0.35%. However, the equivalent dose of menthol alone (0.4%) was not fully effective against nematode egg eclosion. The anthelmintic activity of the essential oil of M. piperita showed good effectiveness in previous studies but also showed the presence of toxic compounds such as pulegone which could be toxic to goats according to allometric extrapolation. Our results show that the major component in the essential oil is not the only one responsible for the antiparasitic effect of M. piperita. Also, our data support the idea there is a wide variation in the composition of essential oils obtained from different sources. Thus, it is important that in assessing anthelmintic activity of plant candidates, the chemical composition should be thoroughly investigated before proceeding to the in vivo step.

O emprego da biotecnologia para o desenvolvimento de novos produtos e processos e de importancia estrategica para o agronegocio brasileiro e mundial. Todos os anos, 40% das safras de alimentos do mundo sao perdidas por ataques de insetos ou fungos. Hoje, no Brasil, gastam-se cerca de US$ 2.5 bilhoes com pesticidas. A transgenia podera ajudar significativamente na reducao destas perdas, trazendo impactos importantes tanto no que respeita a diminuicao dos custos de producao quanto a consevacao do meio ambiente. no ano de 2000 foram cultivados cerca de 44.2 milhoes de hectares com produtos transgenicos em todo mundo. O valor global de sementes de produtos transgenicos cresceu rapidamente de US$ 1 milhao, em 1995, para US$ 3 bilhoes, em 1999. O proposito deste trabalho e apresentar um relato sucinto sobre a importancia, as perspectivas e os impactos dos produtos transgenicos no brasil e no mundo, alguns avancos tecnico-cientificos obtidos e a posicao institucional da Embrapa a respeito do assunto. |
