P. zozimoides is local endemic in Nigde province, Turkey. There has been no previous examination of the chemical composition and bioactivity of that plant extract. In this study, we studied total phenolic content, antioxidant properties and cytotoxic effect of methanolic extracts of plant sample. According to the Folin-Ciocalteau method, the total phenolics of the extracts were determined spectrophometric. The antioxidant activity was conducted DPPH (1,1’-diphenyl-2-picrylhydrazyl) radical scavenging method and free radical reducing power assay. The cytotoxic effect was studied using MTT assay cell viability on cancer cell lines as well as on Caco-2 cell lines. The total phenolic content of P. zozimoides extract was found 28.79±0.68 μg GAE /mg. The free radical scavenger activities of the DPPH was 31.69%±1.61, 85.15%±0.13, 86.96%±0.085 for 1, 5 and 10 mg/mL, respectively. The free radical reducing power assay was 0.375±0.52, 1.587±0.71, 1.798±0.84 for 1, 5 and 10 mg/mL compared to ascorbic acid standard. On Caco-2 cell lines, the extract of plant showed no cytotoxic potential. Because of its phenolic constituents and its antioxidant capacity it can be considered a healthy nutrient.

This study aimed to determine the L-DOPA content in the flowers of some different faba bean genotypes and determine the L-DOPA levels in tea prepared from flowers. The experiment was carried out under the ecological conditions in Samsun by the Black Sea with 15 genotypes using a randomized complete block design in three replications. The flowers were harvested three times and the number of flowers and flower yields were determined. The L-DOPA content of the flower and flower tea were determined using HPLC. Different solvents were used to extract the L-DOPA from the faba bean flowers. As a result of the HPLC analyses, the highest L-DOPA yield was determined to be in the tea samples brewed with hot water. It was found statistical differences between genotypes in the second and third harvests for the number of flowers in the plant and the total number of flowers. Dry flower yields ranged from 11.33 to 37.78 kg da−1 while L-DOPA levels were 6.2 to 9.17 g 100g−1 in dry flowers and 6.69 to 9.23 g 100g−1 in infused tea. The study concluded that flower tea of faba bean can be investigate for medicinal purposes and that L-DOPA in the plant can be extracted by brewing without requiring any solvent. This shows that L-DOPA is in a salt form within the plant.

Purpose: This study aims to reveal the comparative advantage of the selected countries in olive oil industry. These selected countries are the main olive oil producers and mainly located in Mediterranean Seacoast. Spain, Italy, Greece and Turkey will be the subject countries in this analysis and compared with each other in terms of their export performance and comparative advantage in olive oil industry globally. Olive oil industry has a volume of around 20 billion Euros every year. Design/methodology/approach: The data for the research was collected from mainly World Bank and trade ministries of subject countries. Revealed Comparative advantage Index (RCA) is used to compare the advantage of these countries in olive oil industry. These indexes found in this analysis will be added to the olive oil RCA indexes of these countries that are found in the previous researches. The obtained data were analyzed through RCA Index formula modeling. Findings:Consuming olive oil is increasing day by day over the world. The research results show that Turkey has comparative advantage in olive industry over Greece. Last few years, Turkey has improved its comparative advantage over Italy. Spain and Italy are the leading countries in olive oil industry in terms of comparative advantage. It has also been found that Turkey has consistently increase its advantage over the last decade. Practical implications: After the comparison of RCA indexes of Spain, Greece, Italy and Turkey, it is found that higher amount of production of olive oil is not enough itself to improve the competitiveness of a country in olive oil market. Branding, packaging and marketing activities that are supported by research and development expenditures are highly important factors for a consistent competitive advantage in olive oil industry. Olive oil consumers are highly motivated on the packaging and label of a product when it comes to olive oil. They usually trust Mediterranean brands comparing to others. Originality/value: The study answers the advantages of selected countries in terms of olive oil performance in global markets. Export performance of olive oil is much likely to improve the competitiveness of a country rather than a country that produces high volume of olive oil. Production itself is not enough to increase competitiveness of a country in olive oil market.

In this study, it was aimed to determine the total carbohydrate (CHO), minerals and phenolic (total phenolic content, total flavanols, total flavonols, and anthocyanins) of grape and grape products. For this reason, fresh grapes (Kalecik Karası, Öküzgözü, Emir, and Narince), raisins (Karadimrit and Sultani Çekirdeksiz), wines (Kalecik Karası, Öküzgözü, Emir, and Narince), commercial red grape juice, molasses, and vinegar were used as research materials. In conclusion, total CHO contents in the samples were ranged from 0.14 to 48.37 g 100 g-1. In terms of the minerals, molasses was rich in K while the highest contents of P and Fe were found in vinegar. Raisin of Karadimrit contained the highest Ca content among all the samples tested. Not only total phenolic contents but also total flavanols, total flavonols, and anthocyanins were altered depending on the sample types and the varieties. As a result, it was determined that grape and grape products represent a potentially significant source of CHO, minerals, and phenolic.

According to the trend of a healthy eating awareness trend, having a potential benefit on human health, some polyphenols like flavonoids, resveratrol, hydroxy-stilbenes, and phenolic acids are in the spotlight. Grapes, and one of the most widespread grape product wine; are among the best sources of these polyphenols. In this study, a highly specific, susceptible, and easy chromatographic method was brought out and validated to determine 18 polyphenols in grape and red wines. For this aim, an HPLC-PDA was used, and the separation was accomplished on an RP-ODS4 column. The method comprised of a mobile gradient phase consisting of A solution (acetic acid in water, pH 2.00) and a mixture of the solution A – acetonitrile (20:80, v/v), at a flow rate of 1.0 ml/min, and PDA detection was carried out at 260,280, 320, and 360 nm. According to the results, it can be said that the program indicated good linearity over the range of 1-40 mg L−1 of phenolics with r2>0.99. The recovery of the 18 phenolics ranges from 83.17% to 119.88% at red wines and 88.20% to 117.83% at grape juices. The method is well precise, with the relative standard deviation (RSD) of the average concentration of the phenolic compounds are ranges from 1.22% to 2.02% at red wines and 1.01% to 2.56% at grape juices.

In the study, the bioactive, physicochemical and antimicrobial properties of koruk juice and dried koruk pomace were investigated. The total phenolic contents of koruk juice and pomace were determined as 1119.670 and 1182.170 mg GAE/L, respectively. Higher DPPH radical scavenging activity found in koruk pomace, which was consistent with total phenolic contents. Organic acid, total sugar and ascorbic acid contents of koruk juice (3.44%, 4.737 g/L and 2.559 mg/100 mL) were higher than koruk pomace (0.19%, 0.866 g/L and 0.242 mg/100 mL). The counts of Total Psychrophilic Aerobic Bacteria and mold-yeast in pomace were determined as 0.694 and 1.016 log CFU/g, respectively, while no growth was observed in koruk juice. Koruk juice and pomace indicated antimicrobial effect on all test microorganisms in the range of 31.3-500.0 µg/mL (Minimum Inhibition Concentration). The most sensitive bacteria to koruk juice were Bacillus cereus, while Pediococcus acidilactici was the most sensitive one to koruk pomace. Koruk juice also showed bactericidal effect on all test cultures at concentration ranging between 250.0 and 500.0 µg/mL (Minimum Bactericidal Concentration), koruk pomace was not showed bactericidal effect on Escherichia coli O157:H7, Salmonella Typhimurium, E. coli and B. cereus. This study demonstrated that the koruk products could be used in food applications as natural antioxidant and antimicrobial substance.

In this study, it was aimed to determine the polymorphism of GH (growth hormone) gene in Japanese quails and the relationships between these genes and body weight and carcass traits. 3 genotypes (AA, AB and BB), 2 (A and B) alleles were detected by cutting the GH intron 1 region with restriction enzyme MspI. As a result of variance analysis, it was determined that the hatching weights of the animals with B allele and liver weights were higher. Thus, it is seen that GH gene and PCR-RFLP technique can be used in breeding studies.
