Resumo:
Aspidosperma piryfolium and Anadenathera colubrina are typical plants of the caatinga and high occurrence in semi-arid areas of Brazil. They are described in the literature and used for reforestation of degraded forest, shipbuilding and civil building. They are used as medicinal plants by popular knowledge, but there are few studies that prove their effectiveness. The objective of this work was to perform a bromatological and phytochemical studies these plants to characterize them chemically, but also investigate its parasiticide action against the tick Rhipicephalus (Boophilus) microplus. The leaves of A. piryfolium and A. colubrina were colleted at the experimental farm in Patos town, Paraiba state. The experiments were performed in Envirioment Researchs Laboratory (LAMPA) and Animal nutrition Laboratory (LANA), Campina Grande Federal University. After collect, the plants were properly identified and preserved in collections deposited in the Herbarium of the same institution. The leaves collected was dried, ground, weighed and conditioned in glass recipient until to be used. The samples were submitted to cold extraction using ethanol. The crude extracts were utilized to realize the phytochemical. Dry Matter (DM), Mineral Matter (MM), Crude Protein (CP), Ether Extract (EE) were analyzed to determinate the chemical composition. The effectiveness of plant extracts against the cattle tick was tested through the immersion test of engorged, in the laboratory.
