“…According to the current results, our data were actually lower than previous studies (Harif Fadzilah, Jaapar, Jajuli, & Wan Omar, 2017;Vasconcelos, Duarte, Gomes, da Silva, & López, 2017). Vasconcelos et al (2017) publish a study to assess the influence of botanical origin on the physicochemical composition and antioxidant potential of pollen samples from Apis mellifera from the meso-regions of Brazil during a dry season. They found that the phenolic constituents of pollens were exactly affected by the season.…”

ÖzetThis study was related to evaluating the antioxidant of one pollen sample which was collected from Giresun, Turkey. The antioxidant properties of this sample were determined to use total phenolic contents (TPCs), total flavonoid contents (TFCs), proanthocyanidin contents (PCs), and ferric reducing antioxidant power (FRAP) assays. The result of the total phenolic content was 6.33±0.11 mg GAE/ g sample, total flavonoid content was 1.88±0.11 mg QE/g sample, proanthocyanidin content was 0.86±0.00 mg CE/g sample, FRAP was also 72.38±0.21 µmoL FeSO4.7H2O/g, respectively. The obtaining results revealed that the pollen could be seen as a valuable natural source thanks to its significant antioxidant capacity.

“…postica from Chapadinha was more than 2-times that of M. fasciculata from the same city, suggesting that although these bees live in same environment, their habits and plants visited are distinct, which influences the chemical composition of their pollen, and justifies this difference in bioactivity. Regarding the FRAP and ABTS •+ assays, the results are similar to those reported for other bee species, including M. fasciculata [7,39,40]. Neutralization of free radicals is important, since these radicals promote molecular disorders that can cause various diseases [41].…”

Bees are of great importance for plant diversity for being an important pollinating agents. Stingless bees such as Scaptotrigona affinis postica, is cultivated largely due to the products offered by it. Pollen is one of these products, which has been highlighted for exhibit various therapeutic properties. Considering the bioactivity of this natural product, this study investigated the antioxidant, anti-inflammatory, antinociceptive activities, and elucidated the chemical composition of pollen collected extract by Scaptotrigona affinis postica. Using in vitro assays, the antioxidant potential and inhibitory activity against the COX enzyme from pollen extract was evaluated. Additionally, tests were performed to measure the anti-inflammatory and antinociceptive activities in animal models. In our results, we found that pollen extract showed antioxidant effects and inhibitory activity against the COX enzyme. The in vivo assays showed that the extract acts on the nervous system in local and systemic levels and that the anti-inflammatory activity is due the prostanoids reducing. Chemical analyses recognize 10 molecules in the extract belonging to the polyphenol and flavonoids classes and the computational study suggests that is responsible for the observed results. Thus, it is reported for the first time the biological potential of S. aff. postica pollen extract and we conclude that this bee product can be considered as one source of potential new drugs.

“…According to the literature, the highest total phenolic compound content coinciding with this study were recorded in propolis samples and the lowest found in honey. Other researchers showed that the total phenolic compounds content in ethanolic beebread extracts ranged from 2.5 to 13.7 mg gallic acid equivalents (GAE)/g [37], in 50% ethanolic honey solutions from 0.38 to 0.86 mg GAE/g [38], in ethanolic propolis extracts from 269.6 to 426.9 mg GAE/g [39], in ethanolic bee pollen extract from 7.6 to 25.9 mg GAE/g [40]. In our study lower values were obtained, as water was used as extraction solvent.…”

The aim of this study was to compare the physichochemical composition of various bee products, namely, bee pollen, beebread, propolis, honey, and royal jelly. The samples (37 out of 53) were collected in Lithuania, several samples from other Europe countries (Italy, Denmark, Sweden, Slovakia, Poland, Spain, Republic of Malta, The Netherlands, Latvia, Ukraine) were used for comparison. Various quantities, such as pH, electrical conductivity, oxidation-reduction potential, NaCl content, refraction index, Brix value, total phenolic compound content, total flavonoid content and antiradical activity were measured. Together with the mentioned, the content of micro- and macroelements (As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, Se, Sr, V and Zn), ultraviolet-visible spectroscopy absorption spectra were analysed. To our knowledge, the literature data about comprehensive comparison of various characteristics of bee products are scarce. Also, to the best of our knowledge, this is the first study revealing mineral content in Lithuanian bee pollen, beebread and royal jelly. The study exposed that bee pollen not only showed the highest values of pH, electrical conductivity and content of soluble solids, but also distinguished from the other samples by the highest flavonoid content (up to 48.3 mg/10 g), the absence of Cr, the presence of Co (0.011–0.100 mg/kg) and Sr (0.73–5.37 mg/kg) and the highest content of Ca (997–2455 mg/kg) and Mg (644–1004 mg/kg). Hierarchical clustering analysis was applied to group the tested samples according to the physicochemical analysis results and mineral content. The clustering analysis revealed that bee pollen formed separate group with the highest distance from the other samples in both cases.
