MIC of hydroethanolic extract of A. absinthium ranged between 31.25 mg / ml and 500 mg / ml, and he had resistance to three strains: P.aeruginosa К pneumoniaeXXA and A. baumannii^. The therapeutic action of medicinal plants resulting from the combination of common and specific therapeutic properties of certain constituents, “secondary metabolites” (natural products) [Dias, 2012]. Phenols have a major role in protecting plants against herbivores and enzyme inhibitors. Thus, numerous studies have revealed their role in the resistance against fungi, bacteria and nematodes. In these interactions, it seems that the speed and duration novo biosynthesis of phenolics resistance is more important than the constituent concentrations 48 500 250 125 62,5 31,25 15,625 7,831 3,9 1,953 0,976 * P. mirabilis 11 A. baumannii 115 —•— P. aeruginosa 111 K.pneumoniae 115 ......P.aeruginosa 120 • K.pneumoniae 114 A.baumannii 15 • P.aeruginosa 125 • A.baumannii 125 ....
