Abstract

NASCIMENTO, Érica Maria; FURLONG, John; PIMENTA, Daniel Sales  and  PRATA, Márcia Cristina de Azevedo. Anthelmintic effect of hidrolact of Mentha villosa Huds. (Lamiaceae) in gastrointestinal nematodes of cattle. Cienc. Rural [online]. 2009, vol.39, n.3, pp. 817-824.  Epub Feb 06, 2009. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782009005000017.

Currently, it has been of great interest to study the anthelmintic activity of medicinal plants in ruminants. Mentha villosa Huds. (Lamiaceae) is one of the mint species that has been popularly used based on various medicinal properties, even for the control of nematode infections. This study aimed to test the anthelmintic activity of hidrolact of this plant, both in vitro, by the quantitative coproculture method, and in vivo, in calves infected with gastrointestinal nematodes, through the egg count reduction test in feces of the hosts. In in vitro tests, the hidrolact at the concentrations 40%, 60% and 80% and 100% obtained percentage of effectiveness of 91.88%, 94.15%, 98.40% and 100% respectively, showing significant ovicidal activity against gastrointestinal nematodes in calves. However, the hidrolact of M. villosa showed no in vivo anthelmintic activity at 0.1ml kg-1 day-1 on the treated animals.
