An Investigation on the antimicrobial activity of some endemic plant species from Turkey
(2008-01-04) Benli M.; Bingol U.; Geven F.; Guney K.; Yigit N.
In this study performed on six endemic plant species, antimicrobial activity was observed in Campanula lyrata subsp.lyrata and Abies nordmanniana subsp. bornmuelleriana plants. The minimum inhibitory concentration of C. lyrata subsp. lyrata (leaf and flower) extract was found to be ≥ 29 mg/ml for Baccillus subtilis and ≥ 14.5 mg/ml for Staphylococcus aureus, and the minimum inhibitory concentration (MIC) of Abies nordmanniana subsp. bornmuelleriana (leaf) extract was found to be > 314 mg/ml for B. subtilis and when minimum bacteriocidal concentration (MBC) results were evaluated, it was observed that the plant extracts had bacteriocidal effects. No antimicrobial activity was observed in the other plant extracts, namely, Onosma bornmuelleri (leaf- flower), Dianthus balansae (leaf- flower), Alyssum pateri subsp. pateri (seed) and Scabiosa columbaria subsp. paphlagonica (leaf) extracts that were tested. © 2008 Academic Journals.
Antimicrobial activity of endemic digitalis lamarckii Ivan from Turkey
(2009-03-01) Benli M.; Yiǧit N.; Geven F.; Güney K.; Ümit B.
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
(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.
