Article Antidiabetic and Antioxidant Effects of Vitis Vinifera L. Cv. 'kara Erik' Seed Extract in Streptozotocin Diabetic Rats(Scibulcom Ltd., 2017) Yildirim, B.A.; Kordali, S.; Yildirim, S.; Yildirim, F.; Ercisli, S.In this study was aimed to investigate effects on the levels of liver and renal tissue CAT, MDA, SOD, GPx and GSH activities of Vitis vinifera L. cv. 'Kara Erik' seed extract on diabetic rats. A total of 28 male rats were randomly divided to four groups containing of 7 rats per group. Control Group: Received only vehicle 0.5% Carboxymethyl cellulose (CMC), STZ-DM (Streptozotosin-Diabetus mellitus) Group: Streptozotocin 60 mg/kg/IP single dose, VVE (Vitis vinifera L. seed extract) Group: Vitis vinifera seed extract 100 mg/kg/20days/po, STZ-DM+VVE Group: STZ as 60 mg/kg/IP single dose + VVE100 mg/kg/20days/po. At the end of these processes, the animals were sacrificed, liver and renal tissue were excised by dissection and evaluated. Catalase (CAT), Malondialdehyde (MDA), Superoxide dismutase (SOD), Glutathione peroxidase (GPx) and Glutathione (GSH) were measured in the liver and renal homogenisates. VVE was shown that the activity of CAT, SOD and GSH activities increased and decreased levels of MDA in diabetic rats. As a result, the results showed that oral administration of VVE extract reduced the levels of lIPid peroxides and improved the antioxidant activity in liver and renal tissues in rats treated with V. vinifera seed extract as compared with the diabetic and control rats. These results suggested that the V. vinifera L. cv. seed extract enhanced the antioxidant defense under hyperglycaemic conditions hence protected the liver and renal cells.Article Chemical Composition and Antioxidant Activity Ziziphora Clinopodioides Ecotypes From Turkey(Ars Docendi, 2016) Alp, S.; Ercisli, S.; Dogan, H.; Temim, E.; Leto, A.; Zia-Ul-Haq, M.; Aladag, H.The chemical composition of essential oil from eight ecotypes of Z. clinopodioides sampled from different points of Coruh valley located in Northeastern Turkey was determined and its total phenolic content and antioxidant activities were also evaluated. Seventeen components, representing 88.56-96.83% of the essential oil were identified by GC-MS. Differences between total phenolic content (varied between 43.41 and 55.71 mg GAE/100 g fresh weight base) and antioxidant activity (ranged from 3.60 to 4.20 mg/ml in DPPH assay) for the essential oil obtained from plant material harvest from different ecotypes were observed. The main components of all samples include (+)-pulegone, 1,8-cineole, limonene, menthol, beta-pinene, menthone, piperitenone and piperitone. Z. clinopodioides essential oil, total phenolic content and antioxidant activity affected by ecotype and environment conditions. The present study provides a theoretical basis for the potential application of essential oil from Z. clinopodioides to be used as a natural resource of antioxidant agents in food industry. The results also support the traditional use of Z. clinopodioides in Turkish folk medicine.Article Extraction and Identification of Volatile Compounds in Rosa Laxa Retz Var Harputense T. Baytop "kişmiri Rose(Centenary University, 2022) Alp, S.; Zarifikhosroshahi, M.; Yasa Ozturk, G.; Ercisli, S.The gardening of ornamental plants comes back to ancient times (Urartians). Nowadays the gardening of ornamental plants is done worldwide as in the Van provinces of Türkiye. Old and traditional gardens can be seen in different regions of this province naturally. Among these plants, Rosa laxa Retzius var. harputense T. Baytop (Kişmiri rose), is an exotic plant coming from Central Asia. Kişmiri rose has semi-double and miniature flowers and blooms for about five months in the ecological conditions of Van. It has not only highly decorative but also has a light, pleasant, and enthusiastic fragrance. As far as we know there is no previously published on the volatile profile of Rosa laxa Retz var. harputense (Kişmiri rose). For this purpose, in this study, "Headspace Solid Phase Micro Extraction Gas Chromatography-Mass Spectrometry" (HS/SPME/GC/MS) was applied for the detection of volatile compounds of Kişmiri rose flowers. A total of 31 compounds of Kişmiri rose were identified and quantified using Gas Chromatography-Mass Spectrometry (GC/MS). Among these identified compounds, phenyl ethyl alcohol (26.59%), cis-3-hexenyl acetate (18.573%) was detected as the major ones. According to the obtained results, it is concluded that our species has also a Chinese origin. © 2022, Centenary University.

Native species grown in their natural ecosystems could be exploited as new foods, valuable natural compounds and derivatives. In the last few years, interest in the rose hip as a fruit crop has increased considerably due to its nutritive and health promoting values. The study was conducted between 2005 and 2006. Among 5000 natural growing rose hip plants around the Van region were examined and among them 26 genotypes were selected. Thirteen genotypes belong to Rosa canina. The fruit weight, length and width of genotypes were ranged between 1.79-4.95 g; 15.28-33.83 mm and 13.11-19.26 mm, respectively. Soluble solid content ranged from 17.73% (VRS132) to 28.45% (VRS 234). Ascorbic acid levels ranged between 517 to 1032 mg/100 ml. The phenotypically divergent genotypes identified in this study could be of much use in the future breeding program.Article Morphological and Chemical Diversity Among Hawthorn (Crataegus Spp.) Genotypes From Turkey(Academic Journals, 2011) Yanar, M.; Ercisli, S.; Yilmaz, K. U.; Sahiner, H.; Taskin, T.; Zengin, Y.; Celik, F.Anatolia had been known to have rich hawthorn gene pool including diverse genotypes adapted to different local conditions in different regions of the country. Long-term seed propagation and also human selection revealed a great diversity of hawthorn plants in Anatolia. In this study, the morphological (fruit weight, dimensions, fruit skin color, flesh/seed ratio, plant habits and thorn situation) and chemical (pH and soluble solid content) characteristics of 21 selected hawthorn genotypes belongs to Crataegus monogyna ssp. monogyna Jacq, Crataegus monogyna ssp. azarella Jacq, Crataegus pontica K.

A wide variation was found among genotypes in both intra and inters level on most of morphological and chemical properties. Fruit weight varied from 0.65 to 4.19 g among genotypes. Fruit skin color were determined as light green, yellow, light orange, orange, red and dark red. SSC (soluble solid content) of genotypes ranging from 6.40 to 16.0%. In general, most of the genotypes had tree form and also had various degree of thorn on its plants.Article Screening Biological Activity of Essential Oils From Artemisia Dracunculus L(Scibulcom Ltd, 2015) Kumlay, A. M.; Yildirim, B. A.; Ekici, K.; Ercisli, S.Recently have been observed a rise in the consumption of herbal medicines, including medicinal and aromatic plants. Tarragon (Artemisia dracunculus L.) became a popular plant by using widely in food industry and pharmacy. The plant was distinguished by the presence of essential oils, polyacetylenes, as well as lignans, sesquiterpenes and flavonoids. The composition of the essential oils of tarragon growing wild in Eastern Anatolia region of Turkey was investigated. Essential oils of the aerial parts of tarragon were isolated using the hydro-distillation method and their chemical constituents were determined by capillary gas chromatography-mass spectrometry (GCMS) in combination with retention indices. GC-MS analysis revealed the presence of 1,8-cineole (35.88%), camphor (32.28%), camphene (9.13%), bomeol (7.07%), thymene (3.31%), terpinen-4-ol (3.26%), gamma-terpinene (1.32%), alpha-terpineol (1.29%), caryophyllene oxide (1.28%), and f3-pinene (1.10%) as major components. Essential oils of tarragon extracts were screened for antibacterial activity against three gram-negative (Pseudomonas aeruginosa, Salmonella typhimurium and Escherichia coli) and three gram-positive (Staphylococcus aureus, Bacillus subtilis and Enterecoccus faecalis) bacteria. All tested bacteria were sensitive to the essential oils of tarragon at a concentration of 20%, with the inhibition zones ranging from 10 to 15 mm. The essential oil of tarragon showed less antibacterial activity compared to the chemical antibiotics ampicillin and ofloxacin.Article Seed Oil Profiles of Five Rose Hip Species (Rosa Spp.) From Hakkari, Turkey(Wfl Publ, 2010) Celik, F.; Balta, F.; Ercisli, S.; Kazankaya, A.; Javidipour, I.The seed oil of rose hip is mainly used for cosmetic and medicinal purposes. This study deals with detecting the seed oil contents of five rose hip species growing in Hakkari, Eastern Turkey. By GC, seed oil contents were determined as 4.97% for Rosa canina, 5.26% for Rosa dumalis var. boissieri, 6.59% for Rosa pulverulanta, 5.44% for Rosa iberica, and 7.95% for Rosa heckeliana subsp. vanheurckiana. Seeds contained 4.25-5.15% of palmitic acid, 0.22-0.89% of palmitoleic acid, 1.80-2.43% of stearic acid, 20.35-23.03% of oleic acid, 41.14-51.06% of linoleic acid, 19.66-23.83% of linolenic acid, and 0.94-1.29% of arachidic acid depending on the species. The contents of saturated fatty acid were between 7.39% (Rosa heckeliana subsp. vanheurciana) and 8.84% (Rosa dumalis var. boissieri). The contents of unsaturated fatty acids ranged from 83.28% (Rosa dumalis var. boissieri) to 91.57% (Rosa heckeliana subsp. vanheurciana). The oleic, linoleic and linolenic acids were major fatty acids in all rose hip species.
