Bee products are an important source of nutrients and bioactive phytochemicals. This study aimed to determine the chemical composition (proximate composition, general phytochemical composition, sugar, and phenolic profiles) of four different products (honey, bee pollen, bee bread, and propolis), obtained from the same apiary, as well as to assess their biological activity through antioxidant and enzyme inhibition assays (α-amylase, α-glucosidase, lipase, AchE, neuraminidase, angiotensin-converting enzyme, urease, trypsin, tyrosinase, carbonic anhydrase, thioredoxin reductase, adenosine deaminase). Clear differences were observed among the samples in terms of both chemical composition and biological activity. The analysis revealed that bee pollen exhibited the highest carbohydrate content (87.9%), while propolis was identified as the richest source of phenolic compounds (14,858.9 mg/kg) among the analyzed samples. Propolis exhibited the highest biological activity in all applied antioxidant assays (CUPRAC, DPPH•, and ABTS•+) and in most enzyme inhibition assays. Notably, the α-glucosidase inhibition activity of propolis was comparable to that of the reference standard. In addition, honey exhibited remarkable trypsin inhibition, also comparable to the applied standard. These findings highlight the diverse bioactivities of hive products, which could play a key role in promoting health and preventing diseases.

İncele - Kitap BölümüAçık Erişim2024Phenolic Acids in Pollen
Kostić, Aleksandar Ž.; Gercek, Yusuf Can; Bayram, Nesrin Ecem
Determination of phenolic composition of pollen has been one of the most popular topics over the past decade. Although most research studies focused on bee-collected pollen samples, it was also observed that phenolics, in particular, phenolic acids, are very important as protecting compounds in floral pollen grain, attached to sporopollenin. Based on the collected data a pronounced diversity of phenolic acids and derivatives was observed in pollen samples with different botanical/geographical origin. In total, 23 phenolic acids were identified/quantified in the samples with great predominance of the following ones: caffeic acid (0.04–450 μg/g), ferulic acid (0.27–450 μg/g) and p-coumaric acid (0.14–410 μg/g). However, the highest content was observed for vanillic acid (4985.5 μg/g) in the rape bee-collected pollen (China). In addition, several different derivatives, such as ethers, esters or amides, were also identified in pollen.
