Assessment of Palynological Characterization and Total Phenol-Flavonoid Content of Some Honeys from Ordu in Turkey

Öz

Honey is one of the important honey bee products and varies total phenolic and flavonoid contents depending on mainly its floral source. In this study, the total phenolic-flavonoid content and pollen composition of fifteen honey samples were investigated from Ordu in Turkey. According to melissopalynological (qualitative) analysis, eleven honey samples were unifloral (Castanea sativa (9); Rosaceae (1) and Onobrychis spp.(1)), while four samples were multifloral. The forty-two pollen types from the samples were identified. The melissopalynological (quantitative) analysis based on Maurizio’s Class demonstrated that one in Class II, three in Class III, one in Class IV and ten in Class V. Total phenolic and total flavonoid amunts in these honeys varied from 32.5-171.05 mg GAE (gallic acid equivalent)/100g, 1.65-38.75 mg CAE (catechin equivalent)/100g, respectively. According to this study the highest flavonoid levels obtained from Sample 9 (multifloral) and the highest phenolic contents were shown in sample 1 (C. sativa). This study contributes to literature about Ordu honeys.

Türkiye’nin Ordu iline ait Bazı Balların Palinolojik Karakterizasyonu ve Toplam Fenol-Flavonoid İçeriğinin Değerlendirilmesi

Öz

Bal, en önemli arı ürünlerinden biridir ve total fenol ve flavonoid miktarı floral kaynağına göre değişkenlik gösterir. Bu çalışmada Türkiye’nin Ordu ilinden alınan 15 bal örneğinin toplam fenol, toplam flavonoid ve polen dağılımı incelenmiştir. Melissopalinolojik (qualitatif) analizlere göre 11 bal unifloral (Castanea sativa (9); Rosaceae (1) and Onobrychis spp.(1)), dört örnek multifloraldır. Örneklerden 42 polen tipi tanımlanmıştır. Maurizio’s Sınıflandırmasına dayanarak yapılan mellissopalinolojik (quantitatif) analizler  1 tane Class II, 3 tane Class III, 1 tane Class IV ve 10 tane Class V olduğunu göstermiştir. Bu ballardaki toplam fenol ve flavonoid içerikleri sırasıyla 32.5-171.05 mg GAE/100g, 1.65-38.75 mg CAE/100g aralığında değişmektedir. Bu çalışmaya göre en yüksek flavonoid seviyesi örnek 9 (multifloral)’dan elde edilmiştir ve en yüksek fenol içeriği örnek 1 (C. sativa)’de gözlenmiştir. Bu çalışma literature Ordu balları hakkında katkı sağlamaktadır.
