Phytochemical Screening and Antibacterial Activity of Menthe Piperita, Artemisa Compestris L and Pelargonium Adoraitissimum Leaves Extracts from North Libya

Phytochemical screening of the menthe piperita, artemisa compestris L and pelargonium adoraitissimum leave extracts from north Libya revealed the presence of some bioactive components. Various chemical tests showed that the bioactive compounds are found in methanolic extracts of these plants such as flavonoid, alkaloids, resins, terpineol, volatile oils and tannin groups. Saponin is present in Pelargonium adoraitissimum while it is absent in Menthe piperit and Artemisa compestris. The effects of methanolic extracts on some pathogenic: two strains of gram negative bacteria [Escherichia coli and Klebsiella pneumonia] and two strains of gram positive bacteria [Staphylococcus aureus and strrptococcus spp.] indiated that the menthe piperita has greater inhibition zone against two tested Gram negative bacteria and strains of gram positive bacteria
