AbstractEthnopharmacological relevance: Propolis is a bee product with numerous biological and pharmacological properties, such as immunomodulatory and anti-inflammatory activities.It has been used in folk medicine as a healthy drink and in food to improve health and prevent inflammatory diseases. However, little is known about its mechanism of action.Thus, the goal of this study was to verify the antioxidant activity and to explore the antiinflammatory properties of propolis by addressing its intracellular mechanism of action.Caffeic acid was investigated as a possible compound responsible for propolis action. Materials and Methods:The antioxidant properties of propolis and caffeic acid were evaluated by using the 2,2-diphenyl-1-picrylhydrazyl free radical (DPPH) scavenging method. To analyze the anti-inflammatory activity, Raw 264.7 macrophages were treated with different concentrations of propolis or caffeic acid, and nitric oxide (NO) production, a strong pro-inflammatory mediator, was evaluated by the Griess reaction. The concentrations of propolis and caffeic acid that inhibited NO production were evaluated on intracellular signaling pathways triggered during inflammation, namely p38 mitogenactivated protein kinase (MAPK), c-jun NH 2 -terminal kinase (JNK1/2), the transcription nuclear factor (NF)-NB and extracellular signal-regulated kinase (ERK1/2), through Western blot using specific antibodies. A possible effect of propolis on the cytotoxicity of hepatocytes was also evaluated, since this product can be used in human diets.Results: Caffeic acid showed a higher antioxidant activity than propolis extract. Propolis and caffeic acid inhibited NO production in macrophages, at concentrations without cytotoxicity. Furthermore, both propolis and caffeic acid suppressed LPS-induced signaling pathways, namely p38 MAPK, JNK1/2 and NF-NB. ERK1/2 was not affected by propolis extract and caffeic acid. In addition, propolis and caffeic acid did not induce hepatotoxicity at concentrations with strong anti-inflammatory potential. Conclusions:Propolis exerted an antioxidant and anti-inflammatory action and caffeic acid may be involved in its inhibitory effects on NO production and intracellular signaling cascades, suggesting its use as a natural source of safe anti-inflammatory drugs.

ResumoIntrodução: A própolis é uma substância resinosa e complexa; produzida pelas abelhas, destaca-se por suas propriedades terapêuticas, como atividade antimicrobiana, anti-inflamatória e cicatrizante. Poucos trabalhos existem sobre a variedade de própolis vermelha, encontrada no Estado de Sergipe. Objetivo: Avaliar a ação antimicrobiana do extrato de própolis vermelha, coletada na região nordeste do Estado de Sergipe, contra cepas de Enterococcus faecalis. Material e método: As amostras de própolis vermelha foram coletadas em Brejo Grande-SE, Brasil, e identificadas segundo suas características sensoriais, a granulometria e requisitos físico-químicos. O teor de flavonoides no extrato seco foi determinado. Soluções de própolis vermelha (EEP) foram preparadas nas concentrações de 1%; 2,5%; 5% e 7,5%. A cepa bacteriana de referência utilizada foi Enterococcus faecalis -ATCC 29212. A atividade antibacteriana foi verificada por meio de testes in vitro (teste de difusão em disco e determinação da concentração bactericida mínima -CBM) e ex vivo (utilizando dentes humanos extraídos). No teste ex vivo, os dentes contaminados foram divididos em três grupos com dez dentes cada. O grupo 1 foi tratado com própolis a 7,5% (concentração determinada no teste CBM); o grupo 2 foi tratado como controle positivo, com solução de hipoclorito de sódio a 2,5%, e o grupo 3 foi utilizado como controle negativo, sendo tratado apenas com solução salina NaCl 0,9%. Resultado: O extrato de própolis promoveu halo de inibição comparado ao da solução de hipoclorito de sódio a 2,5%, variando entre 12 e 16 mm. Não houve crescimento bacteriano após irrigação do conduto radicular com a solução de EEP a 7,5%. Conclusão: A própolis coletada apresentou médio teor de flavonoides (1,8%) e características físico-químicas coerentes com as exigidas pelo Ministério da Agricultura. Na concentração de 7,5% de própolis vermelha, foi observado um maior potencial antibacteriano quando comparado aos demais grupos. Descritores: Própolis; bactérias; Enterococcus faecalis. AbstractIntroduction: Propolis is a complex resinous substance produced by bees that has therapeutic properties, such as antimicrobial activity, anti-inflammatory, healing. Few studies exist on the red variety of propolis, found in the state of Sergipe. Objective: Evaluation of the antimicrobial action of the extract of propolis red collected in the northeastern state of Sergipe, against strains of Enterococcus faecalis. Material and method: The red propolis samples were collected in Brejo Grande/SE -Brazil and identified according to their sensory characteristics, granulometry and physical chemical requirements. The content of flavonoids in dried extract was determined. Solutions of red propolis (EEP) were prepared at concentrations of 1%; 2.5%; 5% and 7.5%. The bacterial strain used was Enterococcus faecalis -ATCC 29212. The antibacterial activity was verified by in vitro tests (disk diffusion test and determination of minimum bactericidal concentration -CBM) and ex vivo (using human extracted...

“…Propolis is a product of honeybee colonies that, because of its therapeutic properties, has been widely used in human medicine (Marcucci 1995;Sforcin and Bankova 2011). Because propolis is not normally stored in large quantities in the colony, as is honey, beekeepers induce its production to obtain quantities that permit its commercialization.…”

Increased brood viability and longer lifespan of honeybees selected for propolis production

et al. 2013

-Propolis has been proposed to affect honeybee health. To test this hypothesis, we initially evaluated propolis production in 36 honeybee colonies. The three highest (HP) and three lowest propolis-producing (LP) colonies had mean yields of 16.0 and 0.64 g, respectively. Queens and drones from these parental colonies were crossed by artificial insemination to produce five colonies each of the following crosses: HP♀×HP♂, HP♀× LP♂, LP♀×HP♂, and LP♀×LP♂. Colonies headed by HP♀×HP♂ queens produced 34 times more propolis than those headed by LP♀×LP♂ queens and five times more than those from the other two crosses. Newly emerged bees were marked to measure longevity, and egg and brood counts were made to determine brood survival rates. The colonies with queens derived from crosses between high-propolis-producing colonies had significantly higher brood viability and greater worker bee longevity. We conclude that colonies that collect more propolis are healthier and have longer-living bees.controlled mating / propolis / brood viability / longevity
