“…On the other hand, the origin of sugars in propolis has received almost no comments in the literature. Small amounts of glucose, fructose and sucrose are believed to originate from nectar or honey, introduced occasionally by the bees (Quan, Khan, Watson, & Fearnley, 2008). The question has been raised as to whether the sugars in propolis come from hydrolysed flavonoid glycosides (Quan et al, 2008).…”

However, there are numerous proofs that bees collect propolis from plant materials that contain flavonoid aglycones but no glycosides.…”

The specific chemical profile of Mediterranean propolis from Malta

et al. 2011

View full text Add to dashboard Cite

a b s t r a c tSeventeen Maltese propolis samples were studied by GC-MS after silylation. They exhibited the typical Mediterranean chemical profile, rich in diterpene compounds (18-92% of TIC, GC-MS): 32 individual diterpenes were identified; 22 of them were present in each specimen. The other abundant compound group was that of sugars and sugar derivatives. In some samples, however, another compound group was observed (0-12% of TIC, GC-MS); the corresponding mass spectra were consistent with monoand sesquiterpenyl esters of substituted benzoic acids. Two new propolis constituents of this group, daucane diterpene esters of hydroxybenzoic acids, were isolated. Their origin is suggested to be Ferula communis, as they are taxonomic markers for this species. All propolis samples were active against Staphylococcus aureus but only those with high concentrations of terpenyl esters showed antifungal activity against Candida albicans. The present results confirm that Mediterranean propolis is a valuable natural product with potential to improve human health.

“…The effect of bee pollen on plasma metabolites and ovarian hormones may be due to its vitamins, minerals, phospholipids, balanced nutrient profiles (Leja et al, 2007) and copper contents, which play a role in reproduction (Leja et al, 2007;Xu et al, 2009) and antioxidant factors of bee pollen (Quian et al, 2008;Šarić et al, 2009). …”

Productive and reproductive performance of rabbits does as affected by bee pollen and/or propolis, inulin and/or mannan-oligosaccharides

et al. 2015

The aim of the paper was to compare the effect of prebiotics (inulin and/or mannan-oligosaccharides, MOS) and bee products (bee pollen and/or propolis) on productive and reproductive performance of rabbit does. Seventy nulliparous V-line female rabbits were distributed among 7 groups. The groups were fed the same diet and received no supplements (control group), natural molecules (bee pollen and/or propolis) at 200 mg/kg body weight (BW) or prebiotics (inulin and/or MOS) at 35 mg/kg BW. Productive, reproductive, biochemical and haematological traits were investigated. Bee pollen with propolis significantly increased body weight gain of does 1 wk after mating (3.53%), decreased feed intake (4.49%) and caused larger litter size (39.4%), heavier body weight of litter (17.7%), a greater number of kits born alive (48.7%), higher weight of kits (87.81%) at 28 d of age, higher milk yield (43.6%) and more favourable milk conversion ratio (31.6%). Moreover, bee pollen with propolis had significantly increased plasma total protein (43.1%), albumin (45.7%), globulin (41.0) and progesterone (60.5%), and had a significantly decreased plasma cholesterol (31.1%), aspartate aminotransferase/alanine aminotransferase ratio (20.3%) compared to the control group. Does treated with growth promoters had significantly fewer services per conception (22%) and greater fertility rate (21%) compared to the control group. Inulin with or without MOS significantly increased plasma glucose (49.9 and 50%, respectively) and feed cost (90.2%) compared to the control group. Supplementation of MOS or bee pollen with or without propolis had significantly greater relative economic efficiency (61.9, 55.1 and 27.1%, respectively) than the control group. MOS and bee pollen with or without propolis are able to improve productive and reproductive performance and economic efficiency of rabbit does in comparison to the unsupplemented group.

Physicochemical characteristics of pollen collected by Amazonian stingless bees

2016

View full text Add to dashboard Cite

The purpose of this study was to determine the physicochemical characteristics of pollen collected by the Amazonian stingless bees Melipona seminigra and Melipona interrupta, in order to verify whether their characteristics meet the physicochemical requirements established by the Brazilian Technical Regulation for Identity and Quality of Bee Pollen.Physicochemical analyses were performed through official analytical methods. Results of pollen analyses collected by M. seminigra and M. interrupta were respectively as follows: moisture: 53.39 and 37.12%; protein: 37.63 and 24.00%; lipids: 10.81 and 6.47%; ash: 4.03 and 2.74%; crude fiber: 9.30 and 13.65%; carbohydrates: 25.66 and 44.27%; energy: 350.47 and 331.33kcal%; pH: 3.70 and 3.34; total solids: 46.60 and 62.87%, and water activity: 0.91 and 0.85 foram, respectivamente: umidade: 53,39 e 37,12%; proteínas: 37,63 e 24,00%; lipídeos: 10,81 e 6,47%; cinzas: 4,03 e 2,74%; fibra bruta: 9,30 e 13,65%; carboidratos: 25,66 e 44,27%; energia: 350,47 e 331,33kcal%; pH: 3,70 e 3,34; sólidos totais: 46,60
