Antimicrobial activity of essential oils and ethanol extract of Phlomis fruticosa L. (Lamiaceae)

The essential oils and an ethanol extract of Phlomis fruticosa L. were eval uated for antibacterial and antifungal activities. Seven bacterial and seve n fungal species were used. Among them were human, animal and plant pathoge ns, food poisoning bacteria and fungi which are known as potential mycotoxi n producers. The essential oils showed antibacterial activity against Staph ylococcus aureus, Escherichia coli, Bacillus subtilis, Klebsiella pneumonia e and Micrococcus luteus. The essential oils extracted from the plants coll ected from two different localities showed similar antibacterial activities . The antifungal activity of the essential oils was positive against Asperg illus niger, A. ochraceus, Cladosporium cladosporioides, Fusarium tricinctu m and Phomopsis helianthi. The ethanol extract showed antibacterial activit y against Staphylococcus aureus and Bacillus subtilis and antifungal activi ty against Aspergillus niger, A. ochraceus, Cladosporium cladosporioides, F usarium tricinctum and Phomopsis helianthi.
