  Ucuncu, Osman; Kul, Merve Kalafat; Baltaci, Cemalettin; Aykoc, Ayse Muslu

  This study analyzed the physicochemical characteristics, mineral composition, and antioxidant potential of fifteen floral honey samples collected from five districts of Gümüşhane, Türkiye. The average values for moisture (17.44 g/100 g), insoluble solids (0.04 g/100 g), conductivity (0.35 mS/cm), diastase activity (54.15 DN), free acidity (38.18 meq/kg), and fructose + glucose content (68.95 g/100 g) were mostly within the acceptable limits defined by national honey standards. Proline content ranged from 562.66 to 1466.15 mg/kg, while hydroxymethylfurfural (0.37–18.89 mg/kg) confirmed the freshness of all samples. Potassium, calcium, sodium, and magnesium were identified as the major mineral elements in the analyzed honey samples, with considerable variation observed among samples collected from different districts. Antioxidant activity (Total phenolic content (mg GAE/100 g): 9.21–98.25; SC₅₀ (mg/mL): 5.23–41.29) revealed a strong antioxidant potential of Gümüşhane honeys. This work provides the first detailed characterization of Gümüşhane honeys, confirming their high physicochemical quality, rich mineral profile, and notable antioxidant potential, and underscores their value as a distinctive regional product with functional and commercial significance.

  Research of Peganum harmala: Phytochemical Content, Mineral Profile, Antioxidant, Antidiabetic, Anticholinergic Properties, and Molecular Docking

  İzol, Ebubekir; Turhan, Münire; Yapıcı, İsmail; Necip, Adem; Abdullah Yılmaz, Mustafa; Zengin, Gökhan

  Peganum harmala is a significant medicinal, aromatic plant used in traditional medicine and the subject of many studies. In this study, the phytochemical compound and mineral profile of the plant's ethanol extract were identified quantitatively. Antioxidant properties were determined by total phenolic and flavonoid content, FRAP, DPPH, CUPRAC, ABTS, metal chelating, and phosphomolybdenum assays. Antidiabetic, anticholinergic, and skin care properties were specified by the inhibition of tyrosinase, α-glucosidase, α-amylase, butyrylcholinesterase (BChE), and acetylcholinesterase (AChE) enzymes, respectively. In addition, binding interactions of major phytochemicals with all enzymes were investigated by molecular docking studies. The phytochemical compound of the extract contained significant bioactive components such as acacetin, gentisic acid, p-coumaric acid, quinic acid, rutin, apigenin, and chrysin, while the mineral profile was rich in salt elements. AChE, BChE, tyrosinase, α-amylase, and α-glycosidase enzyme inhibitor results were determined as 2.99 mg GALAE/g, 4.14 mg GALAE/g, 35.8 mg KAE/g, 2.76 mmol ACAE/g, and 1.20 mmol ACAE/g, respectively. As a result, it was identified that it had antioxidant properties and strongly inhibited all enzymes except tyrosinase. The docking scores of major bioactive phytochemicals were found to be high. The best binding pose was obtained by docking acacetin into the active site of AChE (PDB: 4EY7), BChE (PDB: 4BDS), α-glucosidase (PDB: 3WY1), α-amylase (PDB: 6GXV) and tyrosinase (PDB: 2Y9X) receptors. Docking score values were calculated as −10.4, −9.2, −8.8, −7.8, and −7.4 kcal/mol, respectively. Thus, it was revealed that P. harmala has an important potential in drug research and treatment of some diseases.

  Köprüyanı (Maçka-Trabzon) Cu-Skarn cevherleşmesinin jeolojisi ve mineral kimyası özellikleri

  Adem Sivrikaya

  Bu çalışmada, Doğu Pontidler' in Kuzey Zonunda Trabzon ili sınırlarında Köprüyanı mevkiindeki Cu-Skarn cevherleşmesinin; jeolojisi, petrografisi, cevher mikroskobisi özellikleri ve mineral kimyası içeriklerinin belirlenmesi amaçlanmıştır. Köprüyanı cevherleşme sahasında, aktinolit, tremolit, pirit, kalkopirit, manyetit ve malakit mineralleri ile kırık çatlak zonları boyunca gelişmiş limonitleşme, hematitleşme kloritleşme ve epidotlaşma türü alterasyonlar gözlenmektedir. Manyetit minerallerinin genellikle kalkopirit, pirit ve granat ile birlikte bulunduğu, TiO2 içeriklerinin çok düşük (%0.02-1.02) olduğu buna karşılık FeOt içeriklerinin ise %83.13-92.00 arasında değiştiği, türlerinin titonamanyetit olduğu belirlenmiştir. Manyetit ile beraber bulunan ve ekzoskarn zonunda yer alan kalkopirit minerallerinin Cu içeriğinin %33.50-43.27 ve Fe içeriği %29.84-39.11 arasında değiştiği, belirlenmiştir. Epidot minerallerinin Al içeriklerinin yüksek (2.06-2.46), Mn içeriklerinin düşük (0.01-0.03) ve Fe+3 içeriklerinin ise nispeten yüksek (0.59-0.96) olduğu belirlenmiştir. Al bakımından zengin olan epidotların türünün ise klinozoisit olduğu tespit edilmiştir. Granat türleri ağırlıklı olarak andradit ve grossular-andradittir. Pirop+Almandin+Spessartin–Grossular-Andradit üçgen diyagramına göre Köprüyanı cevherleşmesinin Cu-Skarn alanında yer aldığı tespit edilmiştir. Cevher mikroskobisi ve mineral kimyası çalışmaları kapsamında derlenen verilere bağlı olarak, Köprüyanı cevherleşmesinin Cu-skarn tipinde olduğu ve bölgede var olan skarn cevherleşmelerinin parajenez, süksesyon ve mineral kimyası verileri ile benzerlik gösterdiği sonucuna ulaşılmıştır

  Investigation of certain nutritional properties of noodle enriched with raw flaxseed

  Yuksel, F.

  In this study, traditional homemade noodles were enriched with raw flaxseed and some nutritional properties such as resistant starch (RS), total starch, total dietary fibre (TDF), estimated glycaemic index (eGI) and major mineral composition of final products were investigated. Flaxseed was supplemented into the noodle mixture at three different concentrations (10, 15 and 20 g/100 g). RS content of the samples was in the range of 0.61-2.14 g/100 g and the highest RS was found for the sample having 10% flaxseed. Maximum TDF value was determined to be 8.28% for the noodle sample enriched with 20% of flaxseed while that of control was 1.68%. Estimated eGI of the samples was not significantly affected by the flaxseed fortification while mineral composition of noodle samples was significantly affected by the flaxseed addition (P < 0.05). The major mineral compounds present in the samples were sodium, potassium, magnesium and phosphorus. It could be concluded that the noodle enriched with 10% of flaxseed would be a healthier alternative product for consumption.

  Application of cattle manure, zeolite and leonardite improves hay yield and quality of annual ryegrass (Lolium multiflorum Lam.) under semiarid conditions

  Yolcu, Halil; Seker, Hayati; Gullap, M. Kerim; Lithourgidis, Anastasios; Gunes, Adem

  A field experiment was conducted under semiarid conditions to investigate the effect of cattle manure (20 and 40 t ha -1), zeolite (250, 500 and 750 kg ha -1), and leonardite (250, 500 and 750 kg ha -1) applications on hay yield and nutrient quality of annual ryegrass. Application of manure, leonardite, and zeolite increased ryegrass hay yield by 4, 24 and 47%, respectively compared with the control. In all fertilizer levels, the crude protein (CP) content was greater than the control and increased as the level of each fertilizer was increased. Most fertilizer treatments (except from the first level of cattle manure) gave higher CP yield than the control. All fertilizers increased the content of K, S, Ca, Mg, Fe, Mn and B of ryegrass hay as compared with the control, whereas they had no significant effect on Cu and Zn content. The content of most minerals increased as the amount of manure and leonardite applications increased. In conclusion, all fertilizers (especially zeolite) showed great potential for use in organic agriculture as they can improve plant growth and soil conditions in the long term.
