    Bee bread and bee pollen of different plant sources: determination of phenolic content, antioxidant activity, fatty acid and element profiles
    (Springer, 2020) Mayda, Nazli; Ozkok, Asli; Ecem Bayram, Nesrin; Gercek, Yusuf Can; Sorkun, Kadriye
    This study aims to determine the plant sources, fatty acid composition, total phenolic-flavonoid content, antioxidant capacity, and elemental profile of bee pollen (BP) and bee bread (BB) samples from the same bee hive in different locations. 31 families and 71 species were determined by pollen analysis of BP and BB samples. Pollen frequencies in BB samples were generally similar or less than in BP. Total phenolic varied from 8.26 +/- 0.299 to 43.42 +/- 0.779 mg GAE/g, and total flavonoid ranged from 1.81 +/- 0.040 to 4.44 +/- 0.125 mg QE/g. ABTS and DDPH assays indicated that the samples have good antioxidant activity. Samples showed a protein content ranging from 17.6 to 22.2% while the total fatty acid was between 60.27 and 86.49%. The elemental analysis showed that all samples were rich in essential minerals. As a result, total protein, total fatty acids, moisture content and antioxidant capacity of BB samples were found to be lower than those of BP samples from the same hive. In spite of these data, it is necessary to work with more detailed and more samples to be able to say which bee product (bee pollen or bee bread) has superior properties as functional food.

    (2018) Bayram, Nesrin Ecem; Sorkun, Kadriye; Öz, Gül Cevahir; Salih, Bekir; Topçu, Gülaçtı
    Propolis is a resinous substance produced by honey bees from various plants they visit. Sixty-fourpropolis samples were collected from different localities of four districts (Merkez, Yüksekova, Şemdinli, andÇukurca) in Hakkari territory. Ethanol extracts of the propolis samples were prepared, and their chemicalcontents were determined by gas chromatography–mass spectroscopy (GC–MS). Flavonoids were generallyfound in a high concentration in Şemdinli samples of Turkey. Twenty-seven coumarins were identified in the 28propolis samples among studied 64 ones. Except suberosin, the coumarins were never reported before in anypropolis sample with Turkish origin. The propolis samples belonging to Yüksekova were found to be richer incoumarins than the others, and the most richest one among the Yüksekova apiaries, was found to be Akocaksample (Y2) with 41.99% total yield, followed by Akçalı sample (Y5) (30.86%). This is a first comprehensiveand original report about the chemical profile of propolis samples from Hakkari. The propolis samples fromHakkari exhibited a chemical content rich in flavonoids including coumarins and furocoumarins.

    (Gazi Univ, 2019) Ozenirler, Cigdem; Gencay Celemli, Omur; Ecem Bayram, Nesrin; Dikmen, Fatih; Zare, Golshan; Celikbicak, Omur; Sorkun, Kadriye
    The purpose of this study was to contribute toward characterizing the general properties of the Onobrychis Miller (sainfoin) honey. We analyzed 21 samples of Onobrychis honeys, which were collected in 2013, from Northeast Anatolia according to their microscopic and physicochemical features (fructose/glucose (F/G) ratio, 5-(hydroxymethyl) furan-2-carbaldehyde (HMF) value, and volatile compounds). The relationships were examined between these variables with statistical methods such as principal component, regression, and correlation analyses. Statistical analyses revealed certain correlation patterns between several parameters. Onobrychis radiata (Desf.) M. Bieb., O. tournefortii (Willd.) Desv., O. oxyodonta Boiss. and Onobrychis spp. pollens were identified. TPN-10 ranged from 6532 to 481157 while the HMF values were between 0.1-7.5 mg/kg and F/G ratios were between 0.8-1.3. Alcohols, aldehydes, aliphatic acids and their esters, carboxylic acids and their esters, hydrocarbons, flavonoids, ketones, sugars and vitamins were identified in the honey samples within ranges of 0-11.95%, 0-16.76%, 0-24.72%, 0-1.86%, 0-14.71%, 2.74-7.09%, 0-27.02%, 5.12-51.39%, and 0-21.36%, respectively. Although it was not significant, a positive correlation between flavonoids and Onobrychis pollen number was calculated via correlation analysis. There was no meaningful correlation between Onobrychis pollen number and other parameters. Although a negative trend between flavonoids and sugars was observed, it was not significant. F/G ratio was found to be positively correlated with sugars, HMF, and TPN-10 of which the latter two parameters had significant values. Furthermore, a significant positive correlation between TPN-10 and HMF was also detected.
