“…On the other hand, the TPC of Chinese propolis showed slightly higher values as ranged from 262 to 299 mg GAE/g . Meanwhile, the TPC of our bee pollen extracts (24.22 mg GAE/g) was in agreement with those of bee pollen reported from Portugal (25.3-28.8 mg GAE/g) and Spain (18.6-32.2 mg GAE/g) (Pascoal et al, 2014).The TPC of our honey (0.57 mg GAE/g)was comparable to honey collected in Thailand (0.23-0.73 mg GAE/g) by Jantakee and Tragoolpua (2015) and in Portugal (0.23-0.73 mg GAE/g) by Ferreira et al (2009). However, this value was lower when compared to honey from Brazil (1.05 mg GAE/g) (Sant'ana et al, 2014).The variation of TPC from the bee products from various origins could be attributed to climate and environmental factors such as humidity, temperature and soil composition.…”

“…Lower values of EC 50 on DPPH scavenging assay were obtained for northeast of Portugal, which could be related with the higher total phenols content. However, the strong relation between the phenolic compounds and antioxidant activity was not found for the bee pollen studied by Pascoal et al (2014) and Morais et al (2011), and they did not give any reason.Previous studies have presented the effect of phenolic compounds on antioxidant activity of other natural products. He et al(2015) studied antioxidant activity of Pyruspashia flowers in China, and they found that antioxidant effect of P.pashia flowers was related with phenolics content.…”

Antioxidant activities of bee products from Thailand (honey, bee pollen and propolis) via the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonate)(ABTS) assays were determined. The prediction of the EC50 (the half maximal effective concentration) were studied using the logistic, sigmoidal, dose response, and asymmetric 5 parameters (5P) regression models. The antimicrobial ability was tested against Staphylococcus aureus (TISTR 517), Bacillus cereus (TISTR 687), and Escherichia coli(TISTR 1261). Propolis extract with higher total phenolic content (TPC) exhibited more effective antiradical action against the DPPH and ABTS, followed by bee pollen extract and honey. All four regression models could be used to estimate the EC50 of the bee products. However, the dose-respond and 5P provide the better EC50 prediction for the bee products than the others based on the comparability of their results to those of right-angled triangle method. Thai bee products had effective antimicrobial activities on each test microorganism. The antimicrobial potency of the bee products was ranged in the order: propolis> bee pollen >honey. Results revealed that antioxidant activity and antimicrobial ability of the bee products correlated with the TPC values.

“…The pollen trap is used to scrape off the pollen from the legs of bees as they enter the hive. The scientifi c studies revealed various benefi cial therapeutic and nutritional properties of the bee pollen and enabled the scientists to identify its antimicrobial, antioxidant, antiradical, anticancer, and anti-infl ammatory activities (3). The main constituents of the bee pollen are carbohydrates (13-55 %), crude proteins (10-40 %), crude fi bre (0.3-20 %) and lipids (1-10 %) (4-6).…”

SummaryPalynological spectrum, proximate and fatt y acid (FA) composition of eight bee bread samples of diff erent botanical origins were examined and signifi cant variations were observed. The samples were all identifi ed as monofl oral, namely Castanea sativa (94.4 %), Trifolium spp. (85.6 %), Gossypium hirsutum (66.2 %), Citrus spp. (61.4 %) and Helianthus annuus (45.4 %). Each had moisture content between 11.4 and 15.9 %, ash between 1.9 and 2.54 %, fat between 5.9 and 11.5 %, and protein between 14.8 and 24.3 %. A total of 37 FAs were determined with most abundant being (9Z,12Z,15Z)-octadeca-9,12,15-trienoic, (9Z,12Z)--octadeca-9,12-dienoic, hexadecanoic, (Z)-octadec-9-enoic, (Z)-icos-11-enoic and octadecanoic acids. Among all, cott on bee bread contained the highest level of ω-3 FAs, i.e. 41.3 %. Unsaturated to saturated FA ratio ranged between 1.38 and 2.39, indicating that the bee bread can be a good source of unsaturated FAs.

“…The three most important groups of compounds with antioxidant properties in bee pollen are flavonoids, phenolic acids, and tannins (Mǎrghitaş et al, 2009;Pascoal et al, 2014). The mechanisms of antiradical activity are different according to the chemical structure of each compound (Denisow and Denisow-Pietrzyk, 2016).…”

Agr. 45(1): 51-63. Bee pollen is a conglomerate of plant pollens, and its nutritional contents include bioactive compounds with antioxidant/antiradical potentials. These potentials are conditioned by botanical origin. In Chile, the native flora is diverse and promising in terms of bioactive compounds, but many plants grow in metal-polluted areas. The associated bioaccumulation could negatively affect the antioxidant/antiradical abilities of bee pollen. To assess the relationship between the bioaccumulation of metals and the antioxidant activity of pollen, complete bee pollen was collected near and far from the Llaima Volcano, albeit in ranges that ensured the same botanical origins. Mellisopalynological analysis determined Escallonia rubra pollen was the most abundant native flora in complete bee pollen. Therefore, E. rubra pollen collected near and far from the Llaima Volcano was evaluated for the following: phenolic compounds via colorimetric assays; antioxidant activity via ferric reducing/antioxidant power assays; antiradical activity via 1,1-diphenyl-2-picrylhydrazyl radical assays; and metal contents via inductively coupled plasma optical emission spectrometry. Llaima samples had higher Cu and Fe but lower Mn contents and lower antioxidant and antiradical capacities than did the control samples. These results were supported by subsequent fortification assays in Llaima E. rubra samples. In fortified samples with significantly higher metal contents, antiradical and antioxidant abilities decreased. Moreover, shifts in migration times were found for naringenin, rutine, and caffeic acid after capillary electrophoresis (CE) analysis in fortified samples. In conclusion, the results indicated an inverse correlation between metal contents and antioxidant/ antiradical potentials in bee pollen.
