    Antimicrobial and Herbicidal Activities of the Essential Oil from the Mediterranean Thymus eigii
    (Taylor & Francis Ltd, 2018) Ulukanli, Zeynep; Cenet, Menderes; Ince, Huseyin; Yilmaztekin, Murat
    Essential oil (EO) of Thymus eigii (Lamiaceae) was hydrodistillated and characterized using with GC/MS. Forty-three constituents were determined accounting 100 % of the EO. The predominant constituents were thymol (24.77 %), carvacrol (14.00 %), p-cymene (10.91 %), -terpinene (6.53 %) and borneol (6.48 %). EO showed different levels of antimicrobial activities on test microorganisms. C. albicans, C. parapsilosis and S. aureus ATCC 29213 had the MIC/MFC/MBC values with 0.07/0.18 mg/ml, 0.18/0.36 mg/ml and 0.36/1.22 mg/ml respectively. EO of T. eigii exhibited pronounced herbicidal activities by inhibiting the germination and the growth of the seedlings of all plant species.

    Chemical composition, antimicrobial, insecticidal, phytotoxic and antioxidant activities of Mediterranean Pinus brutia and Pinus pinea resin essential oils
    (Chinese Journal Natural Medicines, 2014) Ulukanli, Zeynep; Karaborklu, Salih; Bozok, Fuat; Ates, Burhan; Erdogan, Selim; Cenet, Menderes; Karaaslan, Merve Goksin
    Essential oils of the resins of Pinus brutia and Pinus pinea were evaluated for their biological potential. Essential oils were characterized using GC-MS and GC/FID. In vitro antimicrobial, phytotoxic, antioxidant, and insecticidal activities were carried out using the direct contact and the fumigant assays, respectively. The chemical profile of the essential oils of the resins of P. pinea and P. brutia included mainly a-pinene (21.39% and 25.40%), beta-pinene (9.68% and 9.69%), and caryophyllene (9.12% and 4.81%). The essential oils of P. pinea and P. brutia exerted notable antimicrobial activities on Micrococcus luteus and Bacillus subtilis, insecticidal activities on Ephestia kuehniella eggs, phytotoxic activities on Lactuca sativa, Lepidium sativum, and Portulaca oleracea, as well as antioxidant potential. Indications of the biological activities of the essential oils suggest their use in the formulation of ecofriendly and biocompatible pharmaceuticals.

    Essential Oil Constituents of Tanacetum cilicicum: Antimicrobial and Phytotoxic Activities
    (Wiley-Hindawi, 2017) Ulukanli, Zeynep; Demirci, Salih; Yilmaztekin, Murat
    Aerial parts of Tanacetum cilicicum were hydrodistillated for 3 h using Clevenger. Essential oil (EO) yield was 0.4% (v/w). According to the GC/MS analyses, EO of T. cilicicum consisted of monoterpenes [alpha-pinene (2.95 +/- 0.19%), sabinene (2.32 +/- 0.11%), and limonene (3.17 +/- 0.25)], oxygenated monoterpenes [eucalyptol (5.08 +/- 0.32%), camphor (3.53 +/- 0.27%), linalool (7.01 +/- 0.32%),alpha-terpineol (3.13 +/- 0.23%), and borneol (4.21 +/- 0.17%)], and sesquiterpenes [sesquisabinene hydrate (6.88 +/- 0.41%), nerolidol (4.90 +/- 0.33%),alpha-muurolol (4.57% alpha 0.35), spathulanol (2.98 alpha 0.12%), juniper camphor (2.68 alpha 0.19%), (-)-caryophyllene oxide (2.64 +/- 0.19%), 8-hydroxylinalool (2.62 +/- 0.15%), and A-cadinene (2.48 +/- 0.16%)]. In the antimicrobial assay, MIC/MBC values of the EO were the most significant on B. subtilis (0.39/0.78 mu L/mL) and B. cereus (0.78/1.56 mu L/mL). The most prominent phytotoxic activities of the EO were observed on L. sativa, L. sativum, and P. oleracea. The results of the present study indicated that EO of T. cilicicum includes various medicinally and industrially crucial phytoconstituents that could be in use for industrial applications. The finding of this study is the first report on this species from the East Mediterranean region.

    Essential oil constituents, antimicrobial and herbicidal assays of lesser calamint (Calamintha nepeta (L.) Savi subsp. nepeta) from East Mediterranean Region of Turkey
    (Amg Transcend Assoc, 2016) Ulukanli, Zeynep; Demirci, Salih Cercis; Yilmaztekin, Murat
    Calamintha nepeta (L.) Savi subsp. nepeta (Lamiaceae) has a widespread use in the mint family of the Angiosperms. Uses of the spectacular aromatic feature as well as immense medicinal properties of this species have been dated back to the antiquity in the Mediterranean life. Aerial parts of the Calamintha nepeta (L.) Savi subsp. nepeta were collected from the wild ecosystems of the Amanos Mountains (East Mediterranean of Turkey). The hydrodistillated essential oil (EO) of the species were predominantly rich in with the following constituents; pulegone (43.02%) and menthone (28.09%). EO of the tested species had also notable antimicrobial activities. Minimum Inhibitory and Bacterio/Fungio-Cidal Concentrations (MIC and MBC/MFC) of C. nepeta' EO were 0.39/0.78 mu l/ml for B. subtilis, 0.19/0.78 mu l/ml for C. albicans and 0.78/0.78 mu l/ml for C. parapsilosis. In the herbicidal assay, a 100% inhibition of the seed germination, radicle and plumule growth of L. sativa was found at 0.5, 1.0 and 2.0 mg/ml of the EO. The germination and seedling lengths of P. oleracea and L. sativum in response to 1.0 and 2.0 mg/ml of the EO treatment were the same as those found for L. sativa. Essential oil composition, antimicrobial as well as the herbicidal assays of the species from Amanos Mountans (East Mediterranean region of Turkey) could be regarded as the first report.
