Classification and Causes of New Species (V. edremitense) which was included in Veronica beccabunga L. subsp. muscosa [(Korsh.) A.Jelen., 1971)] before. Öztürk, Avni; KILIÇ, ÖMER In this study, Veronica beccabunga subsp. muscosa is one of the subspecies of Veronica beccabunga, which is understood from more detailed studies that some population (F 1001) samples collected and included to – subsp. muscosa in 2000 year; then as a result of more detailed studies came out that it should not be include in -subsp. muscosa, it should be classified as a separate and new species called Veronica edremitense A.Öztürk & Ö.Kılıç. As a matter of fact, when the population sample (F 1001) was examined more detailed, and when compared with Veronica beccabunga subspecies, there are significant morphological and caryological differences. Because of the reasons described in this article we would like to call our population sample as a newspecies called “V. edremitense A.Öztürk & Ö.Kılıç” which was collected from Edremit county of Van.

New remarkably Silene L. species (Caryophyllaceae) from Bingöl provinces. YILDIRIMLI, ŞİNASİ; KILIÇ, ÖMER Perennial S. magenta Yıld. & Kılıç (Caryophyllaceae) are described and illustrated as new species from Bingöl, east Turkey. The distributions of the new and closely related species are mapped. S. magenta is closely related to S. hamzaoglui and S. phyrigia, respectively.

Potential nutrıtıve value of Astragalus species harvested at three different maturity stages. ÇAÇAN, ERDAL; ÜLGER, İSMAİL; YILMAZ, M.F.; KILIÇ, ÖMER; KÖKTEN, KAĞAN; KAPLAN, MAHMUT The present study was conducted to investigate the effects of maturity stages on the chemical composition, in vitro gas and methane production, metabolic energy and organic matter digestibility for eleven Astragalus species widely encountered over the rangelands and intensely grazed by ruminants. Astragalus samples were collected from the rangelands at three different stages namely as before flowering, flowering and bear fruit stages. Dried samples were then subjected to various chemical analysis. Effects of Astragalus species and maturity stages on chemical composition, in vitro gas and methane production, metabolic energy and organic matter digestibility were found to be quite significant (P < 0.001). Acid detergent fiber (ADF) and neutral detergent fiber (NDF) ratios increased, while the crude protein, crude ash, crude oil, condensed tannin contents, gas and methane production levels decreased with the progress of maturity stage. It can be suggested that grazing was more favorable at before flowering or flowering stages of Astragalus species because of high crude protein and metabolic energy content of plant at these stages. Also, although all Astragalus species were considered as a quality feed source for ruminants, endemic Astragalus oocephalus and Astragalus longifolius species were prominent with their superior nutritive properties.

Chemical Composition and Antibacterial Activity of Cardamine uliginosa Bieb. Growing Wild in Eastern Region of Turkey.

Chemical Composition and Antibacterial Activity of Cardamine uliginosa Bieb. Growing Wild in Eastern Region of Turkey. KILIÇ, ÖMER; Özdemir, Fethi Ahmet Cardamine uliginosa Bieb. is a native plant belonging to Brassicaceae family which can used in ethnomedicine. This study was carried out to evaluate the essential oils composition of Cardamine uliginosa and its antibacterial activity. The plant sample was analyzed by GC/GC-MS system. Eventually twenty four components representing 91.2% of the total oil were identified. The obtained results proved the presence of twenty four components. The major component essential oil of this plant were identified as; limonene (32.6%), caryophyllene oxide (28.5%), -caryophyllene (8.4%), p-cymene (3.4%), α-terpinolene (3.3%), β-pinene (2.4%), α-copaene (2.1%), α-longipinene (1.3%), -cadinene (1.2%) and -ocimene (1.0%) was determined. The antibacterial activity of the essential oil was determined against sixteen bacterium isolates by measuring inhibition zones produced by the oil. The antibacterial activity of C. uliginosa essential oil was tested using the disc diffusion method wherein the essential oil has shown notably antibacterial effect with the inhibition zone in diameter from 2 mm (for Pseudomonas aeruginosa DSM 50070) to 11 mm (for Bacillus subtilis IM 622), with the exception of Salmonella enterica ATCC 1331 and Salmonella typhimurium NRRLE 4413 where the oils haven’t shown antibacterial activity. Also weak inhibitory effect were observed against Enterobacter aerogenes CCM 2531, Escherichia coli ATCC 25922, Pseudomonas aeruginosa DSM 50070 and Proteus vulgaris. Chemical composition and antibacterial activity of the tested Cardamine uliginosa essential oil, obtained from plant material from the eastern region of Turkey, display a significant phytomedical potential.
