    Physicochemical properties, phytohormone profiles and quality assessment of honey from the Çoruh Valley of Türkiye

    Tosun, Murat; Cengiz, Mahir Murat; Erdoğan, Yaşar; Turan, Metin

    In this study, seventeen floral honey samples collected from Türkiye’s Çoruh Valley were examined and a total of 59 parameters were analyzed to evaluate their quality attributes. Accordingly, hydroxymethylfurfural (HMF), diastase activity, fructose, glucose, sucrose, total fructose + glucose (F + G), the fructose/glucose ratio (F/G), color and δ13C isotope values were determined together with amino acid profiles, organic acid composition, mineral contents, and phytohormone profiles. All chemical and biological data were evaluated using multivariate statistical approaches, including Principal Component Analysis (PCA), Pearson correlation analysis and Hierarchical Clustering Analysis (HCA), to characterize similarities and differences among the samples. The analytical results demonstrated that honeys from this region comply with established quality standards and exhibit natural purity, balanced chemical composition, and favorable nutritional properties. The detection of diverse phytohormone types and concentrations across the samples, as revealed by the analyses, indicates a rich biochemical signature originating from plant sources. This finding also highlights the functional properties, biological value, and nutritional significance of these honeys. Overall, the results confirm that the floral honeys obtained from Türkiye’s Çoruh Valley are high-quality products in terms of both chemical and biological properties.

    Synergistic Strategies for Overcoming Salt Stress in Strawberry Farming: The Use of Organic Fertilizers and Plant Growth Promoting Rhizobacteria (PGPR)

    Yavuz, Aysegul; Erdogan, Ummugulsum; Turan, Metin; Argın, Sanem; Kocaman, Ayhan

    The study was carried out under salt-stress conditions, and three non-microbial commercial organic fertilizers purchased from Humintech GmbH (Grevenbroich, Germany) were applied to the soil for strawberry plants. The three promoters were Fulvagra®, based on fulvic acid, Liqhumus®, based on humic acid, and Microsense Root®, also based on humic acid. Treatment with Fulvagra® resulted in a remarkable 69.90% increase in average fruit weight and a 39.52% increase in yield in strawberry plants. These improvements remained significant when combined with plant growth promoting rhizobacteria (PGPR), resulting in a 61.81% increase in fruit weight and a 45.21% increase in yield. Liqhumus® treatment resulted in a significant 49.95% increase in fruit weight and a 39.30% increase in fruit yield. The introduction of PGPR further enhanced these effects by increasing fruit weight by 87.70% and yield by 63.84%. The Microsense Root® treatment showed 31.07 and 61.87% improvements for the respective parameters. In conjunction with this treatment, the use of PGPR produced the most significant results, with increases of 121.14 and 65.37% for respective parameters. These results indicate that the combined use of non-microbial commercial organic fertilizers with PGPR leads to higher efficiency and is promising for sustainable agricultural practices, particularly in improving the resistance of strawberry plants to salt-induced stress.

    Boztaş, Kadir; Gercek, Yusuf Can; Türer, Gizem; Canlı, Deniz; Bayram, Sinan; Çelik, Saffet; Kırkıncı, Seran; Basturk, Fatma Nur; Feizollahi, Sepideh; Cevahir Öz, Gül

    By-products with remarkable bioactive properties are formed in extraction processes of essential oils from plant materials. In present study, it was aimed to determine the concentration of individual phenolic and organic acid compounds by LC-MS/MS of the by-product (wastewater) collected after the essential oil isolation from Pelargonium graveolens L. and to determine some bioactive properties of this by-product. In addition, the chemical analysis and antibacterial activity of the essential oil extracted from P. graveolens were determined and the histo-anatomical characterization of the glandular trichomes in the leaf sample was performed. As a result, quercetin (95862.22 μg/kg), myricetin (59834.32 μg/kg) and rutin (36522.90 μg/kg) were the phenolic compounds determined in the highest concentrations in the by-product extracted using two different extraction techniques (non-hydrolysis and hydrolysis methods). Moreover, the individual organic acids of the by-product screened in LC-MS/MS was found to be 4487.17 mg/kg in total. When the essential oil component profile of the plant sample was examined, the citronellol (38.78%) compound was found to be dominant, and it was also detected that the essential oil had remarkable bioactive properties. In conclusion, it can be stated that both the essential oil obtained from P. graveolens and the by-product obtained during essential oil isolation can be considered as a source of some bioactive components in many different industrial applications.

    Organic acids and their derivatives: minor components of bee pollen, bee bread, royal jelly and bee venom

    Çelik, Saffet; Gerçek, Yusuf Can; Özkök, Aslı; Ecem Bayram, Nesrin

    This study aimed to determine the organic acid profiles of bee products such as royal jelly, bee venom, bee pollen and bee bread, as well as to verify the method employed in the study. For this purpose, royal jelly, bee venom, bee pollen and bee bread samples were obtained from different locations, and 55 individual organic acids were determined using the liquid chromatography technique coupled with tandem mass spectrometry (LC–MS/MS), and method verification was carried out. Moreover, principal component and hierarchical cluster analyses were performed to compare the organic acid content of bee products and evaluate the overall variation. According to the results, the order of the total organic acid profiles was determined as bee venom (4141 mg/kg-6260 mg/kg) > bee bread (736–990 mg/kg) > bee pollen (837–1503 mg/kg) > royal jelly (192–1947 mg/kg). Although citric acid (423–41,519 mg/kg) was dominantly detected in samples among the organic acids screened. It is thought that the results obtained will contribute to scientific studies carried out to determine the authenticity of bee products and their standardization.

    Akin, Meleksen; Eyduran, Sadiye Peral; Ercisli, Sezai; Yilmaz, Ilker; Cakir, Ozlem

    Blackberry and mulberry are main berry crops grown in Black Sea region mostly in humid shade forest areas and its important for local people's diet and also important for the maintenance of their health and prevention of disease. Present study aimed to determine the content of vitamin C, organic acids (citric acid, tartaric acid, oxalic acid, malic acid, succinic acid, fumaric acid), sugars (glucose and fructose) and phenolic compounds (catechin, rutin, quercetin, chlorogenic acid, ferulic acid, o-coumaric acid, p-coumaric acid, caffeic acid, syringic acid, vanillic acid, and gallic acid), as well as antioxidant capacity (Trolox Equivalent Antioxidant Capacity, TEAC assay) in the wild grown blackberry and mulberry fruit. Among phenolic acids, chlorogenic acid was the predominant for all wild grown blackberries, white and black mulberries. The presence of oxalic acid was only detected in the wild blackberry genotype. As a result, the phytochemical recognition of the wild grown blackberry, black and white mulberries might contribute to forthcoming investigations for developing the efficiency of food industry.

    In this study we report on the content of organic acids, sugars and miner-als in the pulps of the twelve cherry laurel accessions most commonly consumedin eastern Black Sea Region. Malic acid was the dominant organic acid rangedfrom 43.27 (CL6) to 54.23 (CL3) mg/100 g fresh weight basis. The dominantsugars were glucose and fructose in the pulps that ranged from 4.83 (CL1) to5.74 (CL5) mg/100 g and 4.66 (CL3) to 5.53 (CL7) mg/100 g, respectively. Thepulp of cherry laurel was shown to be rich in potassium (187-241 mg), phos-phorus (26-45 mg), calcium (15-22 mg), magnesium (15-24 mg) and sodium(3.9-6.1 mg) in 100 g fruit pulp. The data may be useful in selecting wild ediblefruit species appropriate for incorporation into diets.
