%X A necessidade de encontrar novas drogas eficazes no combate microbiano tem aumentado a cada dia e estimulado a busca de novos compostos naturais com atividades biol¨®gicas. Neste trabalho, realizaram-se estudo fitoqu¨ªmico e an¨¢lises microbiol¨®gicas com os extratos etan¨®licos das esp¨¦cies (jurema-preta) Mimosa tenuiflora (Wild) Poiret e (juremabranca) Piptadenia stipulacea (Benth) Ducke, frente a linhagens de bact¨¦rias patog¨ºnicas. O p¨® da casca do caule de ambas as esp¨¦cies foi submetido ¨¤ avalia  o bromatol¨®gica e determinados os teores de Mat¨¦ria Seca, Mat¨¦ria Mineral, Prote¨ªna Bruta, Fibra em Detergente Neutro e Energia Bruta. Os resultados para a prospec  o qu¨ªmica indicaram a presen a de taninos e outros compostos fen¨®licos, bem como a presen a de saponinas em ambos os extratos. Os extratos das duas esp¨¦cies demonstraram que mais de uma parte das plantas possui atividade antimicrobiana. A composi  o bromatol¨®gica da casca do caule de jurema-preta e jurema-branca apresentou teores diferenciados para as vari¨¢veis avaliadas. The need to find new efficient drugs to combat microbes has increasedthe search for new natural compounds with biological activities. In this work, phytochemical studies and microbiological analysis were carried out with the ethanol extracts of Mimosa tenuiflora (Wild) Poiret and Piptadenia stipulacea (Benth) Ducke on pathogenic bacteria strains. The bark powders of both species were submitted to bromatologic evaluation and the levels of dry matter, mineral matter, crude protein, neutral detergent fiber (NDF) and crude energy were determined. The results of the chemical search chemical showed the presence of tannins and other phenolic compounds as well as the presence of saponins in both extracts. The microbiologic evaluation of the extracts of both species showed that more than one part of the plants had antimicrobial activity. The bromatologic composition of the bark powder of Mimosa tenuiflora (Wild) Poiret and Piptadenia stipulacea (Benth) Ducke showed different contents for analyzed variables.
