Conference Object VARIATION OF FATTY ACID COMPOSITIONS IN CORIANDRUM(CORIANDRUM SATIVUM L. ) CULTIVAR GROWN IN TWO DIFFERENT ECOLOGY(Necmettin Erbakan Üniversitesi, 2017) İzgi, Mehmet Necat; Telci, İsaCoriander, Coriandrum sativum L., belonging Apiaceae family is an important spice plant grown in different locations of Turkey. The study was aimed to investigate the composition of fatty acid compositions of 6 coriander cultivars (Gamze, Arslan, Erbaa, Pelmus, Kudret, and Gürb üz) in two different ecologies of Turkey (Tokat and Mardin). The oils obtained with cold extraction were analyzed by Gas Chromatography. In the Results, total 22 fatty acids were identified in the cultivars. Petroelinic acid was the major fatty acid in all varieties, followed by linoleic acid and palmitic acid. The variation of the major fatty acids was limited in the study. The highest amount of petroselinic acid was changed between 80.5-82.6% and the highest value was reached in Arslan variety in Mardin. Palmitic acid, which is saturated fatty acid in all varieties, was found high in Mardin, while unsaturated fatty acid linoleic acid in Tokat. It was concluded that the effect of regions on fatty acids was little in the study.Article ÇUKUROVA KOŞULLARINDA Hyoscyamus niger' DE (SİYAH BANOTU) FARKLI EKİM VE HASAT ZAMANLARINlN DROG VERİMLERİ VE ALKALOİT ORANLARINA ETKİSİ(Ç.Ü.

Sowed At Different Times(4th International Symposium of Medicinal and Aromatic Plants Symposium, 2018) İzgi, Mehmet Necat; Telci, İsaThis study aims to determine the proper sowing time for the growers of black cumin, a species of the Nigella sativa and N. damascena species of Nigella genus. The study was carried out under the climatic conditions of Mardin plain during 2011-2012 and 2012-2013 vegetation periods. The plants were sowed in four different times: two times in autumn (November 10 and November 25) and two times in spring (March 03 and March 17). Agronomical and quality characteristics of the species sown four different times were investigated in the study. It was found a significant difference between sowing times for all the characteristics examined in the study. In the 2-year average, the seed yield of sativa (3725.8 kg/ha) was found to be higher than that of damascena (2829.0 kg/ha). Higher yields were obtained in both species in autumn sowing. The study determined that damascena, which is more susceptible to cold climate, is not affected by winter sowing in the region and that autumn sowing should be preferred more for both species to obtain higher yields.Article Bazı Tıbbi ve Aromatik Bitkilerin Köklendirme Özellikleri Üzerine Optimum IBA Dozlarının Saptanması(Bitlis Eren Üniversitesi Fen Bilimleri Dergisi, 2020) İzgi, Mehmet NecatBu çalışma; perlit köklendirme ortamında farklı IBA dozlarının (kontrol, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, 5000 ve 5500 ppm) Lavanta, (Lavandula angustifolia Mill.), yağ gülü (Rosa damascena Mill.), kadıntuzluğu (Berberis thunbergii DC) ve biberiye (Rosmarinus officinalis L.) bitkilerinin çelikle köklendirilmeleri üzerine etkisini belirlemek amacıyla yürütülmüştür. Mardin Büyükşehir Belediyesi Fidanlığından 2018 yılında anaç bitkilerden alınan çelikler, 11 farklı IBA dozunda maruz bırakılarak perlitte, sera ortamında dikimleri yapılmıştır.

Species (Apiaceae)(Turkish Journal of Pharmaceutical Sciences, 2020) Önder, Alev; Çınar, Ahsen Sevde; Yılmaz Sarıaltın, Sezen; İzgi, Mehmet Necat; Çoban, TülayObjectives: In the present study, the antioxidant potency of ethyl acetate (AcOEt) and methanol (MeOH) extracts from the aerial parts of Seseli L. species was investigated for the first time. Materials and Methods: Seseli species L. such as Seseli andronakii Woronow ex Schischk., S. campestre Besser, S. corymbosum Boiss. & Heldr., S. gummiferum subsp. gummiferum Pall. ex Sm., S. hartvigii Parolly & Nordt, S. libanotis (L.) W.Koch, S. petraeum M.Bieb., S. peucedanoides (M.Bieb.) Koso-Pol., S. resinosum Freyn & Sint., and S. tortuosum L. growing in Turkey were collected and evaluated for their antioxidant capacity by using 1.1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and lipid peroxidation (LPO) inhibition methods. Results: The highest activities as a scavenger of DPPH radicals were found in the AcOEt extracts of S. peucedanoides (M.Bieb.) Koso-Pol (IC50=0.49 mg/mL), and S. libanotis (IC50=0.75 mg/mL); α-tocopherol was used as a positive control. On the other hand, in the LPO assay, the highest activities were determined in AcOEt and MeOH extracts (at 5 mg/mL) of S. tortuosum and S. libanotis (84-94%). Conclusion: This report gives important information about the antioxidant capacity of Seseli L. species. This research on antioxidant capacity proves that the use of some species used in Eastern Anatolia (in salads) is correct. With this screening study performed in Seseli L. species growing in Turkey, in the future, it is planned to isolate antioxidant compounds from the most active strains of Seseli L.Master Thesis Sater (Satureja hortensis L.)'de farklı kurutma uygulamalarının uçucu yağ verim ve kompozizyonuna etkisi(Mardin Artuklu Üniversitesi, 2021) Eliaçık, Gülcan; İzgi, Mehmet NecatBu araştırma, 2020 yılında Mardin ekolojik koşullarında sater (Satureja hortensis L.) bitkisinde farklı kurutma uygulamalarının uçucu yağ oranı ve kompozisyonuna etkisini tespit etmek amacıyla yürütülmüştür.

Allézard, 2023) İzgi, Mehmet NecatThis study was conducted to examine the effect of animal manure and inorganic fertilizers on the scent composition of Rosa damascena Mill. in 2022. Animal manure (AM), nitrogen phosphate (NP 20-20-0), diammonium phosphate (DAP 18-46), monoammonium phosphate (MAP 24-61), and triple superphosphate (TSP) were used as fertilizers, along with a control group. Headspace solid-phase microextraction gas chromatography–mass spectrometry was utilized to analyze the volatile components of roses. Major components were heneicosane (15.89–27.76%), citronellol (8.90–18.30%), nonadecene (7.90–13.83%), geraniol (6.14–8.27%), nerol (3.03–6.90%), eicosane (1.13–7.85%), and germacrene-D (2.41–5.45%). The highest percentages of citronellol (18.3%), nerol (6.9%) and total terpenes (55.77%) were obtained by animal fertilization, while the highest percentage of long–chain (aliphatic) hydrocarbon (43.60%) was obtained by NP (20-20) fertilization. The control group had the greatest level of geraniol (8.27%), followed by applications of TSP and animal manure (7.39% and 7.20%, respectively). Methyl eugenol (ME) was most abundantly produced by TSP (0.85%), whereas it was least abundantly produced by the control group (0.13%). The closest ME (0.20%) to the control group was produced by animal manure application. Based on the findings, it can be concluded that animal fertilization used in organic agriculture enhances the quality of plant essential oils.Article Effects of different nitrogen doses on thymoquinone and fatty acid composition in seed oil of black cumin (Nigella sativa L.)(AOCS AND WILEY, 2021) İzgi, Mehmet NecatBlack cumin,Nigella sativaL. belonging to Ranunculaceae, is a valuablemedicinal plant because of the curative effects of seed and oil. Despite studieson black cumin, there are few studies on the effects of nitrogen on fatty acidcomposition, no records on thymoquinone yield, and the thymoquinone contentof the seed oil. In this study, the effects of different nitrogen doses on the seedoil yield, thymoquinone ratio/yield, and fatty acid compositions were investi-gated. Field studies with nitrogen doses (0, 40, 60, 80, and 100 kg/ha) werestudied using the randomized plot design. As a result of the research, nitrogendoses significantly affected the oil and thymoquinone yields while insignificanton the thymoquinone ratio. The highest oil yield with 501.6 kg/ha was obtainedfrom 80 kg/ha of the nitrogen doses, while the highest thymoquinone yield with10.24 kg/ha was obtained from the control plots. Thymoquinone yields were inthe same statistical group with other nitrogen doses, except for means of100 kg/ha nitrogen doses. Linoleic, oleic, and palmitic acids were major fattyacids of black cumin, and their variations were insignificant in nitrogen applica-tions. The values of butyric, capric, and linolenic acids varied significantly in dif-ferent nitrogen doses. As a result of the study, it was determined that thehighest oil yield was obtained from 80 kg/ha nitrogen application. It has beendetermined that nitrogen doses above 60–80 kg/ha should be avoided for theseed oil and thymoquinone yields in black cumin.Conference Object INTENT-TO-TREAT MEDICINAL PLANTS FOUND IN THE FLORA OF MARDIN PROVINCE OF TURKEY AND NEIGHBORHOOD(2017) İzgi, Mehmet NecatUsage of plants for medicinal purposes is as old as the history of humanity. In the present study, we evaluated the results of a survey conducted with herbalists and people experienced in herbal mixtures who are located in the city center of Mardin, with the purpose of identifying the medicinal plants growing in the flora of Mardin and neighborhood, and as well as their therapeutic uses. In this study, both the local and Latin names of the examined plants, their indented use, the parts of the plant that is used, and preparation methods were specified. Totally 24 plant types were recorded, and some of these plants were used to treat more than one disease. Accordingly, the studied plants were used to treat a total of 34 diseases, with 29 internal and 5 external use. Most common therapeutic use of the plants included regulation of blood sugar level, cardiovascular system, cholesterol and circulation, respiration, digestion, gastrointestinal disorders, urinary tract disorders, analgesic, burns, and skin diseases. It was determined that most plants were used alone, while some were mixed as mixtures.Conference Object Farklı Kişniş (Coriandrum sativum L.) Popülasyon ve Çeşitlerinde Sıra Arası Mesafesinin Tarımsal Özellikleri ve Sabit Yağ Oranına Etkisi(Kahramanmaraş Sütçü İmam Üniversitesi, 2017) İzgi, Mehmet NecatKişniş, taze yaprak ve olgun meyveleri kullanılan önemli bir baharat bitkisidir. Mevcut çalışmada tescilli Arslan ve Erbaa çeşitleri ile Mardin ilinde, özellikle ova şartlarında yaygın olarak ekilen ve halk arasında Suriye kişnişi olarak bilinen yerel popülasyonun iki farklı sıra arası (17-34 cm) mesafesinde ekiminin verim ve toplam sabit yağ oranlarına etkisi araştırılmıştır. Çalışma 2015-2016 vejetasyon yılında Mardin ekolojik koşullarında tesadüf bloklarında bölünmüş parseller deneme desenine göre yürütülmüştür. Denemede ana parseller sıra arasını, alt parseller ise çeşitleri oluşturmuştur. Olgunlaşma dönemine gelen bitkilerde hasat öncesi bitki boyu, dal sayısı, şemsiye sayısı değerleri belirlenmiştir. Hasat edilen bitkilerin verimleri ile meyve sabit yağ oranları belirlenmiştir. Deneme sonucunda yağ oranları hariç, çeşitler arasında bir fark görülmemiştir. Farklı sıra arası mesafesi ise dal sayısı ile verimi önemli derecede etkilemiş ve 17 cm sıklıkta ekilen bitkilerden daha yüksek meyve verimi (222 kg da-1) alınmıştır.
