Propolis is a resinous substance collected from plants by bees. The propolis composition depends on the surrounding vegetation, the season, and the area from which derive. This hive product usually contains a variety of chemical compounds such as polyphenols (flavonoids, phenolic acids and esters), steroids, and amino acids. The hereditary spherocytosis (HS) is a congenital hemolytic anemia, with origin in the modification of membrane proteins of erythrocytes, which leads to increased susceptibility to hemolysis and a decrease of the cell over-life.

This hive product usually contains a variety of chemical compounds such as polyphenols (flavonoids, phenolic acids and esters), steroids, and amino acids. The hereditary spherocytosis (HS) is a congenital hemolytic anemia, with origin in the modification of membrane proteins of erythrocytes, which leads to increased susceptibility to hemolysis and a decrease of the cell over-life. The HS is the most common red blood cell (RBC) membrane disorder in European Caucasians, with a prevalence of roughly 200-300 per 106, and to Japanese population 5.7-20.3 per 106. The aim of the present work was to determine if propolis extracts could affected the red cell membrane integrity and comparing the effect of two propolis extracts from different regions (Bornes - Trás-os-Montes; Fundão - Beira Interior). In this work, two adults were studied, one with the syndrome HS splenectomized and one healthy used as control. Diagnosis of HS was made by clinical features, identification of spherocytes on peripheral blood smears and abnormal osmotic fragility. The results show that the two propolis extracts affected the erythrocyte membrane fragility in both individuals (control and patient with HS).

Hive products have recently being in the centre of the international scientific community attention, due to its biological properties.Honey is a sweet aliment produced by honey bees and derived from the nectar of flowers. Propolis is prepared by bees througt the collection of resins from trees and flowers. Bee pollen is the male seed of flowers that is collected by honey bees and mixed with bee secretions. The antimicrobial activity of hive products has been studied namely using pathogenic yeasts, regarding their use on traditional medicine. On the other hand, in literature are not reported studies concerning theis bioactivity against fermentative spoilage yeast, however its significance in food spoilage is increasing, essentially due the new food products development. The main objctive of this study was evaluated the effect of three hive products (honey, propolis and pollen - collected in the Northeast of Portugal) against the fermentative spoilge yeast. For this purpose was used fermentative spoilage yeast-Zygosaccharomyces bailli isolated from wine, Zygosaccharomyces rouxii and Zygosaccharomyces melli isolatrd from honey, and Saccharomyces cerevisiae was used as control. Broth diluition was performed in order to evaluted the antifungal activity of these products. The impact of the different hive products on the survival of fermentative spoilage yeasts was analyzed by calculating the percentge of each product...

O “pão de abelha” é um produto da colmeia com origem no pólen transportado pelas abelhas para o interior da colmeia, ao qual é adicionado mel e enzimas digestivas e posteriormente armazenado, nos favos, dando início a uma fermentação lática que lhe confere maior poder de conservação. É uma fonte de nutrientes para as abelhas, rica em proteínas, minerais, gorduras e outras substâncias fundamentais para o desenvolvimento da colonia. Uma das contribuições para o seu elevado valor nutritivo deve-se à presença de uma quantidade significativa de vitaminas e compostos fenólicos, que como antioxidantes naturais, são responsáveis por muitas das suas propriedades biológicas. As potencialidades da aplicação do “pão de abelha” como suplemento alimentar e como nutracêutico depende em grande parte da sua riqueza na composição química a qual varia diretamente com a flora da região e com a época de recolha por parte das abelhas. Neste trabalho estudaram-se 17 amostras de “pão de abelha” do Nordeste transmontano de Portugal, do concelho de Bragança e Vinhais, uma amostra de “pão de abelha” comercial e uma amostra de pólen proveniente também da mesma região, para posteriores comparações durante o estudo. O estudo incidiu na análise da composição polínica...

O pólen apícola resulta da aglutinação do pólen das flores efetuada pelas abelhas, mediante o acréscimo de substâncias salivares e pequenas quantidades de néctar ou mel. Enquanto o mel é armazenado na colmeia dependendo da disponibilidade de néctar na vizinhança da colmeia, o pólen apenas é recolhido pelas abelhas consoante as necessidades da colónia, representando a sua principal fonte de proteínas. A recolha de pólen para consumo humano pode ser realizada através da colocação de um dispositivo capta-pólen à entrada da colmeia o que provoca a queda das cargas polínicas transportadas pelas abelhas nas patas posteriores. Este produto apícola é uma fonte complementar do rendimento do apicultor, mas o sucesso da sua produção é dependente das caraterísticas da flora em redor do apiário e do impacto que a captura de pólen representa na produção de mel. Este trabalho tem por objetivo avaliar e caraterizar, em duas regiões de Trás-os-Montes e Alto Douro, a produção de pólen e o seu o impacto na produção de mel, com a aplicação de diferentes metodologias de recolha. A recolha de pólen realizou-se em quatro apiários, dois no concelho de Vila Nova de Foz Côa e dois no concelho em Bragança. Em três apiários...

Propolis is a resinous hive product collected by honeybees from various plant sources. It has a complex chemical composition, constituted by various phenolic compounds. Extracts of increasing polarity (n-hexane, chloroform, and ethanol) were obtained from a sample of red propolis from the state of Alagoas. Assays were carried out for determination of contents of phenolics, along with antibacterial and antioxidant activities. The EEP, fractions and sub-fractions showed strong biological activities and were related with phenolic the content compounds contents. The sub-fractions were more bioactive than the EEP and fractions, demonstrating that the antioxidant and antibacterial activities are not a result of synergistic effect between the various chemical compounds in propolis.; FAPESP

Baccharis dracunculifolia is the most important vegetal source of propolis in southeast Brazil, and researchers have been investigating its biological properties. Propolis is a complex resinous hive product collected by bees from several plants, showing a very complex chemical composition. It has been employed since ancient times due to its therapeutic properties, such as antimicrobial, anti-inflammatory, antioxidant, immunomodulatory and antitumour activities, among others. The goal of this work was to compare the cytotoxic action of B. dracunculifolia, propolis and two isolated compounds (caffeic and cinnamic acids) on human laryngeal epidermoid carcinoma (HEp-2) cells in vitro. These cells were incubated with different concentrations of each variable, and cell viability was assessed by the crystal violet method. Lower concentrations of B. dracunculifolia (extract and essential oil), propolis, as well as caffeic and cinnamic acids, showed no cytotoxic activity against HEp-2 cells. On the other hand, elevated concentrations (50 and 100 mu g per 100 mu L) exerted a cytotoxic action, and propolis showed a more efficient action than its vegetal source and isolated compounds. Further investigation is still needed in order to explore the potential of these variables as antitumour agents and to understand their mechanisms of action.; CNPq; FAPESP[04/13005-1]; FAPESP[06/59893-0]

Propolis is a hive product containing chiefly beeswax and plant-derived substances such as resin and volatile compounds. Propolis has been used in various parts of the world as an antiseptic and wound healer since ancient times, and interest in the product has recently increased. Considering the lack of data concerning the in vivo mutagenicity of green propolis, the capacity of this natural product to cause damage to the DNA was evaluated, using the alkaline single-cell gel electrophoresis (SCGE) and micronucleus test, in the peripheral blood cells of mice. The doses tested by gavage were 1000, 1500 and 2000 mg/kg. Micronucleus and SCGE assays showed that green propolis caused an increase in the damage to DNA in the peripheral blood cells of mice. The polychromatic: normochromatic erythrocytes ratio was not statistically different from the negative control. Considering the doses and the results obtained in this study, the acute consumption of green propolis produced some mutagenic effects on the blood cells of mice. (C) 2008 Elsevier Ltd.

In order to improve the current chemotherapy of Giardia infection, potential antigiardial agents have been screened, including natural products. Propolis, a resinous hive product collected by bees, has attracted attention as a useful and popular substance with several therapeutic activities. The present study was carried out aiming to evaluate the in vitro effects of an ethanolic extract of propolis on the growth and adherence of Giardia duodenalis trophozoites. Propolis inhibited the growth of trophozoites and the level of inhibition varied according to the extract concentration and incubation times. The highest reduction of parasite growth was observed in cultures exposed to 125, 250 and 500 mu g/ml of propolis, in all incubation periods (24, 48, 72 and 96 h). Growth reduction by 50% was observed in 125 mu g/ml propolis-treated cultures, while the concentrations of 250 and 500 mu g/ml were able to inhibit growth by more than 60%. Propolis also inhibited parasite adherence and all assayed propolis concentrations promoted the detachment of trophozoites. Light microscope observations revealed changes of the pear-shaped aspect of the cell and reduction of flagellar beating frequency in the great part of the trophozoites. Our results hold the perspective for the utilization of propolis as an antigiardial agent. (c) 2005 Elsevier GmbH. All rights reserved.

This study aimed to determine the effect of sucrose ester on the control of Varroa destructor mite infestation in Africanized honeybees. For the in vitro experiments, the product was tested in bees and mites at five concentrations obtained through dilution in water (T0: 100% distilled water; T1: 0.5%; T2: 1%; T3: 2%; T4: 5%; and T5: 10% sucrose ester).For the field studies, the experimental design was completely randomized, with four treatments and seven replicates, totaling 28 colonies, from which seven were the controls, seven were treated with 0.1% sucrose ester, seven with 0.2% sucrose ester, and seven hives with 0.5% sucrose ester diluted in water. In the in vitro study, the sucrose ester at 0.5% concentration caused mite and bee mortality. In the field tests, the product at 0.2% concentration reduced Varroa destructor infestation in Africanized honeybees and, therefore, may be used as a tool to control this pest. At 0.1, 0.2, and 0.5% concentrations, sucrose ester did not impair the establishment of open and capped brood areas, as well as stored food areas in the hive, suggesting it is not toxic to Africanized honeybees.

Mestrado em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de Agronomia; Chestnut honey is an important revenue for beekeepers in Aquitaine. This study aims to understand the influence of different factors: weather, the condition of the colonies, flowering, and the state of the stands of chestnut. The optimum flowering is reached in early July, but these dates seem to vary gretly from one year to another. Two hives were followed with a continuous system register of the weight and weather conditions (temperature, humidity and rainfall). The locations of the two hives have an abundant forest cover, but often older and abandoned. The Gelos hive had a superior production. Within 1500 m, the two apiaries were located in a heavily forested area, dominant chestnut, 65% and 42% of forest land, for Gelos and Ordiarp respectively. Honey production is concentrated in about 8-10 days (late July). This pattern was maintained in two years and in two apiaries. During this period the colonies increased by about 15kg. The period of weight gain corresponds to the flowering chestnut. This is evidence that these two sites chestnut is the main source of nectar. From the peak of flowering, the colonies begin to lose or maintain weight...

The composition and biological activities of propolis, a resinous hive product collected by honeybees from various plant sources, depends on various factors such as season and vegetation of the area. The aim of this study was to evaluate the influence of the seasonal effect on the ethanolic extracts of Brazilian propolis (EEP) type 6 and type 12, collected during 6 months in terms of antibacterial activity and phenolic composition. The antimicrobial properties were evaluated by MIC and MBC on S. mutans Ingbritt 1600 and the profile of chemical composition by UV-visible spectrophotometry, HPLC-RF and GC-MS. The results demonstrated that the season in which propolis is collected influences its chemical composition, resulting in modifications in its antibacterial activity.

Propolis is a hive product containing chiefly beeswax and plant-derived substances such as resin and volatile compounds. Propolis has been used as an antiseptic and wound healer since ancient times and interest for the product has increased recently. Probably few plant species contribute as major resin sources. Green propolis derives mainly from vegetative apices of Baccharis dracunculifolia (alecrim plants). However, wide variation detected in the chemical composition suggests contributions from alternative resin plant sources. Predominant components of the resin of green propolis are cinnamic acids, chiefly compounds bearing prenyl groups. Terpenoid compounds, such as sesqui, di and pentacyclic triterpenoids, have been detected in many, but not all, samples investigated. Propolis research has uncovered potentialities of substances previously isolated from plants and has detected constituents of plant origin that would hardly be known otherwise.

The physical and chemical properties have been determined on 60 samples of crude beeswax, obtained for the most part from beekeepers in California and other Western States, and these properties have been compared with those of freshly secreted scale wax and also with the properties of many of the same crude waxes after they had been decolorized by various processes. For freshly secreted beeswax the properties are nearly constant, but with changes in the quantity and kind of contaminating impurities some or all of these properties change. The physical and chemical properties of the impurities, and not of the waxes as a whole, must therefore be used as the basis for classifying crude beeswaxes. The impurities in crude beeswax consist of honey, suspended particles, or dissolved substances, and may or may not be colored. The soluble colored materials are attributable to substances extracted from pollens, to propolis, and to substances produced by contact of the wax with metals. Darkening of crude wax by contact with iron or oxides of iron is very common. The crude waxes that were highly contaminated with propolis showed higher densities, indices of refraction, acid numbers, and iodine numbers than those containing little propolis but appreciable quantities of other soluble contaminants. Samples high in propolis could not be decolorized by sun bleaching or adsorption...

This article is based on the paper read by Dr. Anna Maurizio at the Bee Research Association Conference on "Flower-bee relationship", help at the Kent Farm and Horticultural Institute at Sittingbourne on 27-29th July 1962. For over thirty years Dr. Maurizio has been engaged in research work on various problems in this field, including pollen analysis of honey, and also bee nutrition in relation to pollen consumption. For her lecture she chose a subject she is at present working on the effect on honey of the various processes the raw material undergoes : in the plant itself, in the bodies of the foraging bees and the house bees, in the cells of the comb, and in the vessel in which the honey is finally stored. Much of this work is so new that it is not yet widely known, and the publication of this paper will bring it within the reach of ùany more people than those who were fortunate enough to hear Dr. Maurizio's lecture.
