    (Natl Inst Science Communication-Niscair, 2009) Benli, Mehlika; Yiğit, Nazife; Geven, Fatmagül; Güney, Kerim; Bingöl, Ümit
    Antimicrobial activity of the methanolic extracts of leaves and flowers of D. lamarckii Ivan, (Scophulariaceae), an endemic plant species of Turkey, was tested on ten bacterial and four yeast strains. Effective antibacterial activity was observed in four bacterial strains. Minimum inhibitory concentration (MIC) was calculated by use of liquid culture tests and in all the four effective bacterial strains, the MIC was found to be >= 199.5 mg/ml. The minimum bactericidal concentration (MBC) of B. subtilis, S. aureus, and L. monocytogenes was calculated to be >= 199.5 mg/ml, and MBC value for Shigella was calculated as >= 399 mg/ml.

    Antimicrobial activity of some endemic plant species from Turkey
    (Academic Journals, 2007) Benli, Mehlika; Güney, Kerim; Bingöl, Ümit; Geven, Fatmagül; Yigit, Nazife
    Six plant extracts obtained from different parts such as the leaves, flowers and seeds of four species of the endemic plants in Turkey were tested on a total of 14 microorganisms, 10 of which were bacterial strains and 4 yeast strains. Verbascum eriocarpum (flower) extract was found to be effective against Staphylococcus aureus; Stachys cretica subsp. anatolica (leaf and flower) and Heracleum paphlagonicum (seed) extracts were found to be effective against Bacillus subtilis; and Alcea apterocarpa (seed and sepal) extract was found to be effective against Pseudomonas aeruginosa. No antimicrobial activity was observed in Heracleum paphlagonicum (leaf) and Alcea apterocarpa (leaf) plant extracts. The minimum inhibitory concentration (MIC) values of the plant extracts were calculated to be between >= 0.859 mg/ml and >= 110.5 mg/ml and the minimum bacteriocidal concentration (MBC) values were calculated to be between >= 3.44 mg/ml and >= 132 mg/ml.
