Abstract The chemical composition of propolis from Bulgaria, Turkey, Greece and Algeria was investigated by GC-MS. All them contained mainly flavonoids esters caffeic ferulic acids, which indicated that their main source are buds poplars the taxonomic section Aegieros. Some Turkish samples a low percent diterpenic while in Algerian significant amounts hydroxyditerpenic acid (M=322, its structure not determined MS) were found. showed antibacterial weak to moderate antifungal activity.
Abstract This study was conducted to determine the characteristic properties of Turkish pine honey, which is an important honeydew honey. The geographical classification honey determined by applying carbon isotope, melissopalynological, and physicochemical analyses 373 samples collected from 47 regions between 2015 2017 under controlled conditions. δ 13 C protein-δ Choney, C4%, electrical conductivity, moisture, ash, free acidity, color CIEL* a*b attributes, optical rotation [α] 20 ,...
This study provides a comprehensive melissopalynological analysis of honey samples from the Ganja Gazakh region Azerbaijan, offering valuable insights into diversity and abundance plant species visited by bees in area. A total 23 were examined using light microscopy to identify quantify pollen types their frequencies. The results revealed that most abundant families Asteraceae, Fabaceae, Rosaceae, Lamiaceae. finding suggests these are important sources nectar for bees. Notably, Fabaceae...
The aim of this study was to determine the chemical and antimicrobial activity two taxa which are important nectar pollen plants for honey bees. Thymus nummularius M. Bieb. Vaccinium myrtillus L. produced by local people Anzer. For purpose, compounds scanned GC–MS system activities were tested against major oral pathogens including Porphyromonas gingivalis ATCC 33277, Streptococcus salivarius DSM 13084, mitis, mutans Candida albicans 90028 agar well diffusion broth microdilution. Aldehydes,...
The aim of the present work is to study chemical composition Turkish propolis. Propolis samples were collected from different regions Turkey (Bursa, Erzurum-Askale, Gumushane-Sogutagil and Trabzon-Caglayan) in 1999. Ethanol extracts propolis (EEP) prepared for analysis, using gas chromatograph coupled with mass spectrometry (GC-MS). Our findings show that Trabzon Gumushane region have a similar composition. In both aromatic acids, aliphatic acids their esters, also ketone derivatives are...
Abstract Atmospheric pollen was collected with a Burkard spore trap in Ankara, Turkey, from January 1990 to 1993. A total of 135.787 grains/m3 belonging 47 taxa were observed. The local season started February and 1991 March 1992. Relatively low concentrations recorded 1992, probably because precipitation wind speed the spring. relatively high concentration which could be caused by higher spring more during winter. Cupressaceae/Taxaceae, Pinaceae, Gramineae, Betula, Moraceae, Platanus,...
The aim of the present study was to investigate antibacterial activities 25 propolis samples collected from various geographical regions Turkey against 2 food-borne pathogens, Salmonella Enteritidis ATCC 13076 and Listeria monocytogenes 1462. chemical compositions ethyl alcohol extracts (EEP) were determined by gas chromatography coupled mass spectrometry. main components EEP flavonoids, aromatic acid esters, alcohols, acids, aliphatic carboxylic terpens, esters. Antibacterial tested at...
Propolis is a resinous material collected by bees from various plants. It has antimicrobial, antioxidative, immunostimulative, and regenerative properties. We determined the scolicidal effect of propolis in different concentrations exposure times.Tubes containing Echinococcus granulosus protoscoleces were supplemented with ethyl alcohol extract propolis. At end incubation times, viability was assessed trypan blue exclusion test. also applied 5 ml 1 microg/ml intraperitoneally for...
We evaluated the effect of oral usage honey and pollen, either separately or together, on postoperative intraabdominal adhesions.Forty rats were randomly separated into 4 groups 10 each. Abrasion was performed cecum, a patch peritoneum located opposite to cecal abrasion completely dissected. Group 1 received no treatment; 2 g/kg/day honey; 3 pollen; pollen mixed in equal amounts, addition standard feeding for 21 days. All sacrificed 21st day. Following adhesion scoring, tissue specimens...
To examine the effects of 10% diluted honey, which has been shown to be scolicidal, on liver and biliary system determine whether it could used as a scolicidal agent in presence biliary-cystic communication.Thirty Wistar-Albino rats were divided into two groups. Honey with dilution study group 0.9% saline (NaCl) control injected common bile ducts through 3-mm duodenotomy. The animals sacrificed 6 mo after procedure. Histopathological, biochemical, radiological examinations performed for...
Propolis is a resinous substance produced by honey bees from various plants they visit.Sixty-four propolis samples were collected different localities of four districts (Merkez, Yüksekova, Şemdinli, and Çukurca) in Hakkari territory.Ethanol extracts the prepared, their chemical contents determined gas chromatography-mass spectroscopy (GC-MS).Flavonoids generally found high concentration Şemdinli Turkey.Twenty-seven coumarins identified 28 among studied 64 ones.Except suberosin, never...
Honeybee pollen is consumed as natural food in healthy human diet many European and Asian countries. The aim of this study was to investigate the effect use on some reproductive parameters. In study, mature male rats were fed three different plant sources (Trifolium spp., Raphine's spp. Cistus spp.) at 60 mg/per animal/ per day over a 30-day period. At end treatment, testosterone levels analyzed weights testis, epididymis, prostate seminal vesicle recorded. addition, epididymal sperms...
Propolis is a resinous material collected by honeybees and obtained from beehives that has anticancer effects inducing apoptosis. The aim of this study to investigate the effect propolis on human telomerase reverse transcriptase (hTERT) in leukemia cells patients. Four different bone marrow cell cultures each four cases were prepared. 60 ng/ml, 30 ng/ml 15 working concentrations administered three patient, while one culture contained only medium. hTERT mRNA expression levels detected at 24...
Ö ZT ürkiye'de genellikle Karadeniz bölgesinde üretilen kestane (Castanea sativa Mill.) ve ormangülü (Rhododendron spp.L.) (delibal) balları içerdiği organik bileşenler yüksek antioksidan seviyeleri ile bilinen önemli ballardır.Bu çalışmanın ilk aşamasında ballarının melissopalinolojik farklılıkları araştırılmış, ikinci ise ormangülü, karışık balların şeker içerikleri kimyasal bileşenleri belirlenmiştir.Bu amaçla Türkiye'nin Bölgesinde, 4 farklı yerden toplamda 18 bal örneği toplanmıştır...
