Antimicrobial Action Of Some Plant Oils

The present investigation was carried out in an effort to open a new area for the possibility of using some plant essential oils as antimicrobial agents. For this purpose, 8 essential oils were studied ”Ocimum basilicum, Carium carvum, Foeniculum vulgare,The main experimental results can be summarized in the following:1- Seventeen microbial species (ten fungi, two yeasts and five bacteria) were isolated and identified from fresh juices of orange, guava and banana incubated at room temperature for seven days.2- The eight essential oils test revealed different degree of antimicrobial activity against these isolates.3- Cymbopogon citratus, Ocimum basilicum and Origanum majoranum essential oils were the highly effective against the microorganisms isolated from juices.4- Aspergillus niger, A. flavus and Saccharomyces cerevisiae were found common in juices and appeared highest resistance against these essential oils.5- GC-MS analysis showed that the main components of Cymbopogon citratus essential oil were e-citral, a-Myrcene and z-citral constituting about 75% of this oil, while Benzynen, 1-methyl-4-(2-propenyl) and 1,8-cineole were the major among17 components cons
