Öğe Effects of sugar type and regional variation on the biochemical composition of royal jelly (Apis mellifera L.)(Nature Portfolio, 2025) Karlidag, Semiramis; Basgel, Serkan; Maras, Zeynep; Uyumlu, Ayse Burcin; Demir, Nurullah; Ugur, Yilmaz; Erdogan, SelimRoyal jelly, owing to its rich biochemical composition, is widely used in apitherapy and human nutrition. To enhance its production, honeybee colonies are often supplemented with industrial carbohydrate sources. This study aimed to investigate how different locations (Do & gbreve;an & scedil;ehir and Uluk & ouml;y) and carbohydrate types influence the biochemical composition of royal jelly, including sugar content, enzymatic activity, and phenolic compounds. The results revealed that both location and carbohydrate source significantly affected the biochemical profile of the samples. The Do & gbreve;an & scedil;ehir-glucose-fed group exhibited the highest 10-hydroxy-trans-2-decenoic acid (10-HAD) content (2.77%, w/w; p < 0.001), whereas the Do & gbreve;an & scedil;ehir-control group had the lowest (1.41%, w/w; p < 0.001). Environmental conditions in Do & gbreve;an & scedil;ehir appeared to promote 10-HDA production, and glucose feeding proved to be an effective strategy for optimizing it. Although glucose, fructose, and sucrose levels were similar between locations, maltose content differed significantly. The highest glucose ratios were detected in the Do & gbreve;an & scedil;ehir bee-feed group (3.82%) and the Uluk & ouml;y bee-feed group (3.57%). Invertase activity (4.51 +/- 1.34 U/mL) and catalase activity (21.78 +/- 0.80 U/mL) were highest in glucose-fed bees, whereas these parameters were lowest in the sucrose-fed group (0.72 +/- 0.16 and 11.25 +/- 2.66 U/mL, respectively; p < 0.01). Glucose feeding markedly increased the levels of invertase, catalase, total protein, amino acids, proline, and 10-HDA in royal jelly (p < 0.01). In conclusion, both environmental factors and carbohydrate-based feeding exert significant effects on the biochemical composition of royal jelly.Öğe Palynological, chemical, antimicrobial, and enzyme inhibition properties of Cannabis sativa L. propolis(Springer, 2023) Ozkok, Asli; Karlidag, Semiramis; Keskin, Merve; Bayram, Sinan; Keskin, Saban; Karabulut, Ercan; Yilmaz, IsmetIn this study, both chemical characterization and biological activities of propolis samples obtained from Cannabis sativa L. (cannabis, hemp, marijuana) isolated colonies (research group) and obtained from colonies at a distance where the bee cannot fly to the isolation area (control group) were determined. Palynological analyses of propolis samples obtained from the research and control group colonies were made and the botanical origin of the cannabis plant and other plants in the research area and the plants in the control group were determined. Bioactive component analysis of propolis extracts was determined by the GC-MS technique. The inhibition effect of propolis samples on some enzymes of medical importance and their antimicrobial effects against many pathogenic microorganisms were also investigated. Palynological analyses showed that honey bees prefer cannabis plants (11.11%) when collecting propolis, and the dry matter percentage (94.6 +/- 1.8%), balsam (46.2 +/- 5.2%), and wax content (4.8 +/- 0.5%), total phenolic (26.44 +/- 1.08 mg GAE/mL) and total flavonoid (2.03 +/- 0.11 mg QE/mL) content and antioxidant capacity (88.16 +/- 2.27 mu M FeSO4 center dot 7H(2)O/mL(-1)) of the research group propolis samples containing hemp were found to be higher than the control group. Also, it was determined that the research group propolis sample contains cannabinoid derivatives (cannabidivarinic acid, 0.29%; delta (1)-tetrahydrocannabinolic acid, 0.59%; cannabidiolic acid, 0.48%), which are active compounds of the cannabis plant. Also, a high inhibition effect was detected on some enzymes of medical importance in propolis samples obtained from cannabis group colonies. In addition, the research group propolis samples also showed a high antimicrobial effect against many pathogenic microorganisms.Öğe POLLEN AND FUNGAL SPORE COMPOSITION VARIATIONS OF HONEYS ACCORDING TO DIFFERENT FEEDING METHODS(Pakistan Botanical Soc, 2023) Yil, Gulsah; Karlidag, Semiramis; Akyol, Abuzer; Koseman, Abdurrahman; Uyumlu, Ayse Burcin; Yilmaztekin, Murat; Seker, IbrahimHoney samples were collected from two districts of Malatya (Eastern Turkey) Battalgazi and Dogansehir for melissopalynological analysis after the honey season in 2018. The survey was conducted to 3 different feeding groups, Glucose, Sucrose, Bee Feed and a Control group in each study area. The samples were prepared according to Louveaux et al., (1978) procedure. Melissopalynological examinations were done to determine both pollen grains and fungal spores for each feeding group and districts. According to the microscopic analyses the dominant pollen types were determined as Astragalus, Cistus, Poaceae, Verbascum, Echium, Berberis, Artemisia, Plantago, Vicia, Onobrychis, Cichorioideae, Astragalus pollen grains were most frequent in glucose and control groups, Cistus pollen grains were widely represented in sucrose and bee feed groups in both study area. Dominant fungal spore types were determined as Aspergillus / Penicillium, Urediniospores, Cladosporium and Myrotechium. Aspergillus / Penicillium spores were dominated almost all samples by varying degrees. Analysis of pollen grains and fungal spores is useful instrument for determining the botanical, geographical and ecological sources of honey. This paper could be guide to beekeepers for selecting convenient apiary domains and appropriate feeding methods for qualitative honeys and the study is also help agriculturists for increasing the crop yield, the bees could be diverting to less-preferred plants during forages by sugar manipulation in order to cultivation improving.Öğe Treatment of injuries in javelin horses with propolis(Univ Zulia, Facultad Ciencias Veterinarias, 2025) Gokhan, Nezihe; Keskin, Merve; Karlidag, Semiramis; Keskin, Saban; Sarici, Oguzcan; Ozyildiz, ZaferDebridement and suturing of deep and infected wounds in horses requires sedation and anesthesia due to the limitations of horses. For this reason, it is preferred to perform wound treatment and care with more practical methods. The aim of this study is to evaluate wound healing in 18 horses by utilizing the antimicrobial, anti- inflammatory and local anesthetic effects of propolis. Various wounds resulting from trauma on 18 male, Arabian and British horses aged between 3-8 at Malatya Equestrian Javelin Club were treated by applying liquid propolis in spray form for 5 days. Wound size was measured with a ruler on days 1, 3, 5, 9, 13, 15 and 21 provides healing in a short time.Öğe Volatile organic compounds of royal jellies obtained from honeybee (Apis mellifera L.) colonies fed with different industrial sugars at different locations(Springer, 2025) Seker, Ibrahim; Karlidag, Semiramis; Akyol, Abuzer; Yil, Gulsah; Koseman, Abdurrahman; Uyumlu, Ayse Burcin; Yilmaztekin, MuratThe aim of this study was to reveal differences in the volatile organic compounds (VOCs) of royal jellies (RJs) produced by honey bee (Apis mellifera L.) colonies fed with 3 different industrial sugars at 2 different locations. VOCs in the RJ samples were extracted via headspace-solid phase micro-extraction and analysed by gas chromatography-mass spectrometry. In total, 46 compounds, including 3 esters, 14 alcohols, 5 acids, 1 aldehyde, 14 ketones, 3 lactones, 2 terpenes and 4 other compounds, were identified in the RJ samples obtained from honeybee (Apis mellifera L.) colonies reared in Do & gbreve;an & scedil;ehir. A total of 45 compounds, including 3 esters, 14 alcohols, 5 acids, 1 aldehyde, 14 ketones, 4 lactones, 2 terpenes and 2 other compounds, were detected in the RJ samples obtained from honeybee (Apis mellifera L.) colonies reared in the Uluk & ouml;y location. It has been determined that different locations and different feeding conditions significantly affect the composition and amounts of volatile organic compounds in royal jelly.
