Aromatics plants have traditionally been used as antibacterial agents and are well accepted today as a source of antioxidants. The present study evaluated the antibacterial activities and antioxidant capacity of eight aromatic plants, indigenous to the flora of the Balkan Peninsula, which are used as medicinal plants in traditional medicine. The plants studied were Hyssopus officinalis, Angelica pancicii, Angelica sylvestris, Laserpitium latifolium, Achillea grandifolia, Achillea crithmifolia, Artemisia absinthium and Tanacetum parthenium. The antimicrobial activities of methanolic extracts of the plant tissues against 16 bacterial isolates of Escherichia coli, Pseudomonas aeruginosa, Klebsiella sp., Proteus mirabilis, Acinetobacter sp., Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae and Enterococcus faecalis were investigated using a microwell dilution assay. Minimal inhibitory concentration (MIC) of the extracts ranged from 6.3 to 100mg mL-1, and minimal bactericidal concentration (MBC) ranged from 12.5 to 1...
