    Chemical Constituents and Antibacterial Activities of Essential Oils of Common Mugwort (Artemisia Vulgaris L.) From Eastern Anatolia Flora
    (Vallecchi Editore, 2016) Yildirim, B.; Kumlay, A.M.; Ekici, K.; Rezaeieh, K.A.P.
    The essential oil components of common mugwort (Artemisia vulgaris L.) and their antibacterial activity were analyzed in the present study. Aerial parts of A. vulgaris plants were collected from natural habitats from Van region of Turkey. Essential oils were isolated using the hydro-distillation method and their components were analyzed by gas chromatography-mass spectrometry (GC-MS). The major components found in essential oil of common mugwort were thujone (60.28%), caryophyllene oxide (11.46%), α-Thujone (9.46%), 1.8 cineole (5.06%), trans-caryophyllene (3.57) and linalool (3.40%). Antibacterial activity of the essential oil was designated against six microorganisms using the disc diffusion method. Essential oils of A. vulgaris extracts were screened for antibacterial activity against three gram-negative (Pseudomonas aeruginosa, Salmonella typhimurium and Escherichia coli) and three gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis and Enterecoccus faecalis). The results illustrated that the essential oils of common mugwort were sensitive; inhibition zones differed to various bacteria such as Escherichia coli ATCC 11775 (14-14 mm), Salmonella typhimurium ATCC 25241 (13-14 mm), Enterecoccus faecalis ATCC 29212 (12-13 mm), Bacillus subtilis ATCC 6051 (12-12 mm), Pseudomonas aeruginosa ATCC 10145 (11-11 mm) and Staphylococcus aureus ATCC 12600 (10-11 mm). The presented results may open new avenues for the development of new phytotherapeutic products from the common mugwort plant species.

    Molecular Characterization of Some Soybean (Glycine Max L.) Varieties
    (Centenary University, 2021) Kumlay, A.M.; Demırel, S.; Demırel, F.; Yildirim, B.
    Global warming and the continuous increasing in human population have adverse effects on the food source. Soybean plays a significant role in human nutrition due to its high protein and fat content. In this study, the genetic relationship of 12 soybean varieties (Nova, Nazlican, SA88, Ataem7, Arısoy, A3127, Türksoy, Adasoy, Yemsoy, ANP2018, Yeşilsoy and Samsoy) was investigated using 6 IPBS markers. According to the results of the IPBS analysis, totally 44 polymorphic bands were obtained and the average polymorphism rate was 85.83%. The average number of polymorphic bands obtained per primer was determined as 7.33. The Dice similarity index between genotypes varied between 0.1 and 0.9091 with the average being 0.4506. According to the results of the analysis, the genotypes showing the closest relationship are Yeşilsoy and Arısoy varieties, while the farthest genotypes are Samsoy and Yemsoy. As a result, IPBS markers can be used effectively to characterize genotypes in the selection of suitable parents in soybean breeding programs. © 2021, Centenary University. All rights reserved.
