Antibiotic resistance is a phenomenon as old as the advent of antibiotics [1]. The development and spread of resistance to currently available antibiotics is a global concern [2]. medicinal plants are important elements of traditional medicine in virtually all cultures. many investigators have demonstrated the antimicrobial activity of the constituents of some higher plants.pseudomonas aeruginosa is recognized as one of the major cause of infections in communities and hospitals. The ability of this opportunistic human pathogen to acquire resistance to a broad range of antibiotics has made effective therapy more difficult [1-3]. imipenem is considered the last line of treatment against a variety of serious infections caused by P.aeruginosa.
