    Antimicrobial activity of some endemic plant species from Turkey
    (2007-08-06) Benli M.; Güney K.; Bingöl U.; Geven F.; Yiǧit N.
    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. © 2007 Academic Journals.

    New Syntaxa for Alliance Astragalo karamasici-Gypsophilion from Central Anatolia (Polatlı-Haymana)
    (2009-01-01) Geven F.; Ketenoǧlu O.; Bingöl U.; Güney K.
    In this study, the steppe vegetation between Polatli{dotless}-Haymana had been analyzed. The study area is located in the southwest part of Central Anatolia covered with the gypsaceous and marly-gypsaceous soils. The vegetation which is under the effective control of semi arid very cold type of Mediterranean climate was analyzed by the three dimensional ordination technique based on the Braun-Blanquet method. Two new associations were described and classified syntaxonomically. These associations which are defined for the first time are named according to the rules of "International Code of Phytosociological Nomenclature". Associations and their higher units are as follows: Class: Astragalo-Brometea Quezel 1973 Order: Onobrychido armeni-Thymetalia leucostomi Akman, Ketenoglu, Quezel 1985 Alliance: Astragalo karamasici-Gypsophillion eriocalycis Ketenoglu, Quezel, Akman, Aydogdu 1983 Association: Salvio-Astragaletum microcephali ass. nova Association: Minuartio-Acantholimetum acerosi ass. nova Phytosociological and phytoecological features of these associations had been discussed and compared with the similar assosiations.
