المستخلص: Today, Libya is by far the most important world source region of medicinal plants collected from the wild. Despite, Libyan countryside provides the most important market with considerable amounts of raw material against many dieses, which have been used for hundred years ago. However, many works have been done elsewhere that aimed to knowing the different antimicrobial and phytochemical constituents of medicinal plants and using them for the treatment of microbial infections in exist way. The increase in number of antibiotic resistant bacteria is no longer matched by expansion in the arsenal of agents available to treat infections. Furthermore, their side effect and cost, many efforts have been made to discover new antimicrobial compounds from plants. This work aims to studying the component activities of four of the well known, very important, volatile plants of medicinal applications, Cymbopogon citratus , Mentha piperita , Ocimum basilicum and Pelargonium graveolens. The study supposing the presence of some chemical components in addition to the volatile oils as main components of leaves of different plants used, different methods have been applied and different kinds of solvents have been used to extract all the chemical substances expected to be effective agents determining the specific pathogenic microbes. Different types of extracts have been investigated for their antimicrobial activities against the growth of different test microorganisms representing different microbial groups (Bacillus subtilis, Pseudomonas aeruginosa, Streptomyces albaduncus, Aspergillus candides, Penicillium expansam and Saccharomyces serevisiae).
