Bee Pollen in Transylvania (Romania): Palynological Characterization and ORACFL Values of Lipophilic and Hydrophilic Extracts of Monofloral Pollen Pellets

ABSTRACT Bee pollen results from the mixture of pollen and floral nectar with the salivary substances of bees and has increasingly been used as a food with therapeutic properties. In this study, 30 samples of bee pollen from Apis mellifera apiaries in three mesoregions of Alagoas (Brazil) - Mata Atlântica, South Coast and Caatinga, were collected during the dry season of 2008/09 and analysed. Mata Atlântica and Caatinga had good production of bee pollen. In the same season, Mata Atlântica contained a higher diversity of pollen types for feeding bees with a predominance of herbaceous pollen (63%), whereas the Caatinga samples contained monofloral pollen. Physicochemical data were analysed with the nonparametric Kruskal-Wallis statistical test. The Caatinga samples were analysed to determine their contents of total phenolic compounds (25.85 ± 10.80 mg gallic acid eq/g) and flavonoids (45.62 ± 32.19 mg quercetin eq/g) and their antioxidant activity (for instance, 70.62 ± 4.50% in the DPPH test), which were possibly affected by the environmental conditions of this biome.

Systemic Health

Background: Bee pollen (BP) has a broad range of beneficial effects on health. The aim of this study was to examine the effect of BP on the oral environment, including the microbiome and antimicrobial peptides. Methods: C57BL/6J mice were randomly divided into two groups: control and BP. The BP group was fed with a 5% BP diet for 1 month. Swabs from the oral and buccal mucosa and samples of the intestinal stool were collected. Genomic DNA was extracted and the microbiome was analyzed via 16S rRNA sequencing. Results: BP inhibited the growth of P. gingivalis at a concentration of >2.5%. The metagenomic study showed that the abundance of genus Lactococcus was significantly elevated in the oral and intestinal microbiomes of the BP group when compared to those of the control group. Significant alterations in alpha and beta diversity were observed between the oral microbiomes of the two groups. The mRNA levels of beta-defensin-2 and -3 were significantly upregulated in the buccal mucosa of the BP group. Conclusion: A BP diet may have a beneficial effect on oral and systemic health by modulating the bacterial flora and antimicrobial peptides of the oral cavity. Further investigations are needed to clarify how a BP diet affects overall human health.

Quercetin Concentration

Nonalcoholic fatty liver disease (NAFLD) is a major cause of morbidity and mortality worldwide. Additional therapies using functional foods and dietary supplements have been investigated and used in clinical practice, showing them to be beneficial. Honeybee pollen from Chile has shown a large concentration of phenolic compounds and high antioxidant activity. In this work, we characterized twenty-eight bee pollen extracts from the central zone of Chile according to botanical origin, phenolic profile, quercetin concentration, and antioxidant activity (FRAP and ORAC-FL). Our results show a statistically significant positive correlation between total phenolic content and antioxidant capacity. Selected samples were evaluated on the ability to reverse the steatosis in an in vitro cell model using Hepa1-6 cells. The pollen extracts protected Hepa1-6 cells against oxidative damage triggered by 2,2′-azo-bis(2-amidinopropane) dihydrochloride (AAPH)derived free radicals. This effect can be credited to the ability of the phenolic compounds present in the extract to protect the liver cells from chemical-induced injury, which might be correlated to their free radical scavenging potential. Additionally, bee pollen extracts reduce lipid accumulation in a cellular model of steatosis. In summary, our results support the antioxidant, hepatoprotective, and anti-steatosis effect of bee pollen in an in vitro model.
