    Antimicrobial activity of centaura derderiifolia, stachys aleurites and anthemis aciphylla
    (2009) Güven, Kiymet; Karabacak, Ersin; Çelik, Sezgin; Uysal, Ismet
    The antimicrobial activity of the ethanol, aseton, ethyl asetate and chloroform extracts from Centaurea derderiifolia Wagenitz (Asteraceae), Stachys aleurites Boiss. (Lamiaceae) and Anthemis aciphylla Boiss. var.aciphylla (Asteraceae) were investigated by agar-well diffusion assay. These extracts were tested in vitro against 26 bacterial and 3 yeast species. Etyhl acetate and acetone extracts of C. derderiifolia, S. aleurites and A. a. var. aciphylla showed antimicrobial activity in varying degrees on all the microorganisms tested. However, chloroform and ethanol extracts of all the plants were not active on some microorganisms tested. Ethyl asetate extracts of the samples exhibited stronger and broader spectrum of antimicrobial activity as compared to ethanol, aseton and chloroform extracts. Therefore, minimal inhibitory concentration (MIC) of only ethyl acetate extracts of the samples was determined for seven bacteria chosen from agar-well diffusion assay. MIC values of the extracts were between 250-125 ?g/ml. In conclusion, ethyl asetate extract of C. derderiifolia was the most active against Aeromonas hydrophila both in agar-well diffusion and MIC assays.

    Canonical correlation analysis for studying the relationship between the basic morphological and some soil chemical characteristics of Centaurea mucronifera DC. (Asteraceae)
    (Chemical Publishing Co., 2008) Çelik, Sezgin; Yücel, Ersin; Mendes, Mehmet; Tug, G. Nilhan; Öztürk, Münir
    This aim of this study was to investigate the relationship between the basic morphological features and some soil chemical characteristics in order to enlighten the differentiation in the Centaurea mucronifera populations distributed at 16 different places under varying environmental conditions. For this purpose method of Canonical correlation analysis (CCA) was used. The results revealed that morphological features like length of terminal leaves (Y3), length of capitula (Y4), length of involucrum (Y5) and length of achen (Y6) are affected positively by N (X6) and Ca2+ (X7) in the soil but the length of plant (Y1), length of basal leaves (Y2) and length of pappus (Y7) are affected negatively.

    Ethnobotanical aspects of Kapıdağ Peninsula (Turkey)
    (2010) Uysal, İsmet; Onar, Sinan; Karabacak, Ersin; Çelik, Sezgin
    Türkiye’nin Kuzeybatı Marmara Bölgesi’nde yer alan ve 300 km2 yüzölçümü olan Kapıdağ Yarımadası, Balıkesir ili sınırları içerisindedir. Bu yarımadada 2004-2006 yılları arasında etnobotanik bir çalışma yapıldı. Bu araştırmada, yarımadada bulunan 7 köye ait 119 kaynak kişi ile görüşülmüştür. Bitkilerin kullanımı ile ilgili olarak elde edilen bilgiler değerlendirildiğinde, tıbbi (33 familyaya ait 44 takson), gıda 21 familyaya ait 40 takson), boya (4 familyaya ait 4 takson), yakıt (4 familyaya ait 4 takson), süs (5 familyaya ait 5 takson) ve diğer kullanım amaçları (11 familyaya ait 12 takson) olarak sınıflandırılmıştır. Sonuçta, toplam olarak 47 familyaya ait 88 takson etnobotanik özellikleri açısından değerlendirilmiştir.

    Plants have been collected from mythological Kazda?i (Mt. Ida) National Park, West Turkey by Turkmens and their folk, cultural and social uses
    (EuroJournals, Inc., 2008) Çelik, Sezgin; Karabacak, Ersin; Uysal, Ismet
    Kazda?i is known in mythology as the Mount Ida (Kazda?i, Goose mount). Homer mentions Mount Ida in his two epic poems, the Iliad and the Odyssey. Afterwards, from the Ottoman times a story has been narrated about Father Cilbak and his yellow daughter (Golden Maiden) in the Kazda?i by the nomadic Turkmens. They have organized the religious ceremony at Kazda?i National Park especially summit area in every August. A lot of plant specimens have been gathered illegally by visitors and local people that live on foot of the mount were established during the ceremony. The investigation records show that 29 taxa are used for medicinal, 12 taxa are used for food and spices, 10 taxa are used for ornament, home goods, and cosmetics. Leaves of 12 taxa (23.5%), stems of 8 taxa (15.7%), fruits of 2 taxa (3.92%), flowers of 3 taxa (5.88%), tuber of 1 taxon (1.96%), roots of 2 taxa (3.92%), bark of 1 taxon (1.92%) are used for single. Different organs of other plants (43.16%) are used together. Sideritis trojana, Thymus pulvinatus, Thymus sipyleus subsp. sipyleus var. sipyleus and Thymus zygioides subsp. lycaonicus of these plants are in danger because of awfully gathering, therefore, conservation suggestion was brought. © EuroJournals Publishing, Inc. 2008.
