Bu çalışma Karadeniz Bölgesi'nde yetişen üç farklı orman gülü (Rhododendron)
türünün yoğun olduğu lokasyonlarda yürütülmüştür. Bu amaçla mor orman gülü
(Rhododendron ponticum L.) için Ordu ili Kent ormanı (Yoroz mevkii), sarı orman
gülü (Rhododendron luteum L.) için Ordu ili Aybastı yaylası ve beyaz orman gülü
(Rhododendron caucasicum L.) için de Rize’nin İkizdere ilçesine bağlı Anzer yaylası
seçilmiştir. Her bir orman gülü bitkisinin bulunduğu lokasyona üç arı kovanı
yerleştirilmiş ve 5 gün bal ve polen toplanmıştır.
Araştırmada, orman gülü (Rhododendron) türlerinden elde edilen bal ve polen
örneklerinin antimikrobiyal ve antioksidan aktiviteleri ile fizikokimyasal özellikleri
incelenmiştir. Farklı orman gülü türünlerinden elde edilen bal ve polen örneklerinde
toplam fenolik içerikleri ve DPPH serbest radikal temizleme aktiviteleri ile
antioksidan aktiviteleri de incelenmiştir. Ayrıca, bal ve polenlerin asetilkolinesteraz
ve butirilkolinesteraz avtivitesi ve lipid peroksidasyonu üzerindeki inhibisyon
potansiyelleri de araştırılmıştır.
Bal için önemli kalite parametrelerinden olan prolin analiz sonuçları incelendiğinde
beyaz orman gülü (Rhododendroncaucasicum L.) balı en yüksek değere sahip olmuş
ve 923,0 mg/kg değer ile diğer orman gülü örneklerinden farklılık göstermiştir. Balın
önemli faktörlerden olan diastaz sayısı 15,5 ile 8,0 arasında değişkenlik göstermiş ve
en yüksek değer beyaz orman gülünde (Rhododendron caucasicum L.) elde
edilmiştir. Tüm orman gülü bal ve polen örneklerinin pUC18 plazmid DNA'sına
karşı benzer etkiler gösterdiği tespit edilmiştir. Prolin miktarı balın kalitesinin
belirlenmesinde önemli bir parametre olup mor orman gülü (Rhododendron ponticum
L.) bitkisinden elde edilen bal örnekleri diğer bal örneklerinden daha düşük değere
sahip olmuştur. Yine orman gülü bal ve polen örneklerinin ham ekstraktlarının
bakteri ve mantarlara karşı belirgin antibakteriyel ve antifungal etki gösterdiği de
saptanmıştır.,This study was carried out to determine the antimicrobial activities, antioxidant
capacities and bioactive components of honeys and pollen obtained from three
different Rhododendron species grown in the Black Sea Region. For this purpose,
Rhododendron ponticum L. grown in Ordu province Urban forest (Yoroz locality),
Rhododendron luteum L. grown in the province of Ordu Aybastı plateau and
Rhododendron caucasicum L. grown in the Anzer plateau of İkizdere district were
chosen. Three bee hives were placed at the location of each Rhododendron plant and
honey and pollen samples were collected for 5 days.
Antimicrobial activities, antioxidant capacities and physicochemical properties of
honey and pollen samples obtained from different Rhododendron species were
investigated. Total phenolic contents and DPPH free radical scavenging activities
and antioxidant activities of honey and pollen samples were also investigated.
Moreover, the inhibition potentials of honey and pollen on acetylcholinesterase and
butyrylcholinesterase activity and lipid peroxidation were examined.
Honey samples obtained from Rhododendron caucasicum L. showed the highest
proline value (one of the important quality parameters for honey) (923.0 mg / kg)
which was significantly, while that obtained from Rhododendron ponticum L. had
the lowest proline value. The diaztase number of honeys, another important quality
factor, varied between 15.5 and 8.0 and the highest value was obtained in the
Rhododendron caucasicum L. All rhododendron species honey and pollen samples
displayed similar effects against pUC18 plasmid DNA. Moreover, raw extracts of
honey and pollen samples of forest rose were found to exhibit significant
antibacterial and antifungal activities against.
