Resumo: The gastrointestinal helminth infections represent one of the main causes in limiting the production of small ruminants around the world. In the search for new alternatives for effective control of these gastrointestinal nematodes, phytotherapy is presented as a promising sector in an attempt to reduce the use of chemical treatments. Making the study of plants with the potential taninífero an alternative anthelmintic control. Once these tannins identified and isolated, it becomes increasingly more practical in its real potential anthelmintic activity. In this sense, we chose species Black Jurema (Mimosa tenuiflora (Willd) Poiret), red angico (Anadenanthera macrocarpa (Benth.) Brenan) and catingueira (Poincianella pyramidalis Tul.) For chemical-bromatological characterization and quantification of the condensed tannin levels in the different fractions of the plant. These Fabaceae were collected in Caatinga area preserved the Sertânia municipality in semiarid region of Pernambuco. Leaf samples were collected with stem and bark of each species and quantification of condensed tannins in the Fabaceae study used the butanol-HCl method. Data were analyzed using descriptive statistics. In this sense, combining obtaining the purified extract of condensed tannin, held anthelmintics trials through larval development tests (TDL) in vitro fecal material collected from Saanen goats naturally infected under management of concentrations in treatments (37.5, 75, 150, 300 and 350 mg/ml) in four replicates each of purified extract of tannins, together with control treatment, positive and negative, with levamisole hydrochloride at a concentration of 7.5 mg / ml and distilled water, respectively. Mimosa tenuiflora (Willd) Poiret. He stood between native Fabaceae with the highest total concentration of tannin, in all fractions of the plant. In anthelmintic activity, significant effect, making it an excellent alternative for controlling gastrointestinal nematodes in small ruminants.
