“…The in vitro antioxidant capacity of Greek bee pollen was affected by the ethanolic extract concentration. The mother bee pollen ethanolic solution (125,000 mg L −1 ) recorded the higher antioxidant capacity (88.26%) followed by those of 30,000 (86.81%), 25,000 (81.75%), 10,000 (71.06%), and 5000 (68.7%) mg•L −1 , respectively (Table 2) Present results are in agreement with previous studies involving American [23], Greek [14], and Algerian [24] bee pollen samples, where the high antioxidant capacity of the respective methanolic extracts was highlighted. It should be stressed that the antioxidant capacity of bee pollen ethanolic extract is strictly related to its phenolic fraction, as it has been well demonstrated in the literature [25].…”

“…In a previous study, total phenolic content of Greek bee pollen methanolic extracts was found higher, ranging between 10.49 ± 0.3 mg of protocatechuic acid equivalents per gram of pollen [14]. The same holds for TPC content values (15.91 ± 0.05-34.85 ± 0.08 mg GAE/g) of different American bee pollen types [23] or Algerian ones (30.46 ± 8.22 mg GAE/g) [24]. However, the observed differences may be also attributed to harvesting year, practices of bee pollen collection and processing, the solvent used for the extraction of polyphenols, along with the plant taxa contribution.…”

The objectives of the present work were: (a) to characterize bee pollen from the region of Epirus in terms of biofunctional activity parameters as assessed by (i) the determination of specific polyphenols using high performance liquid chromatography electrospray ionization mass spectrometry (HPLC/ESI-MS), (ii) antioxidant capacity (DPPH assay), and (iii) total phenolic content (Folin-Ciocalteu assay), and (b) to prepare yoghurts from cow, goat, and sheep milk supplemented with different concentrations of grounded bee pollen (0.5, 1.0, 2.5 and 3.0%, w/v), and study afterwards the trend in antioxidant capacity and total phenolic content along with product’s sensory properties. Results showed that bee pollen ethanolic extracts are a rich source of phytochemicals based on the high total phenolic content and in vitro antioxidant activity that were monitored. The addition of grounded bee pollen in yoghurts resulted in a food matrix of a higher in vitro antioxidant capacity and total phenolic content, whereas it improved the yoghurt’s taste, odour, appearance, and cohesion; the latter indicates its beneficial use as a general food surface and interface material enhancer due to the possible formation of surface/interface active lipid-linked proteins. Based on the present findings, bee pollen yoghurt is proposed as a novel and costless functional food whereas it may comprise a research basis for food or material science in the scientific society of the future. Results were further supported by implementation of advanced chemometric analyses providing a full characterization of the product’s uniqueness.

“…Volume 10, Number 1, January 2020 In this study, the antioxidant activities of bee pollen extracts are associated with the content of phenolic compounds which is similar to the previous reports [19], [20], [21]. On the other hands, this does not appear to be true for other biological activities [22], [23].…”

Bee pollen is a natural product from honeybees which is rich in bioactive compounds. Bee pollen grain and powder were extracted using conventional and sonication extraction methods. All bee pollen crude extracts could not inhibit growth of test pathogenic bacteria. The antioxidant activity was analyzed via DPPH free radical scavenging activity assay and found that the ethanolic extract of bee pollen grain obtained by conventional method had the highest antioxidant activities (p<0.05), 40.69±3.01 mg GAE/g extract. When phenolic content was evaluated, the aqueous extract of bee pollen grain by conventional method showed the highest total phenolic content (103.06±1.96 mg GAE/g extract) while ethanolic extract of bee pollen powder by conventional method exhibited the highest flavonoid content, 56.40±4.85 mg QE/g extract. The data obtained provides the guideline for insightful evaluation of bee pollen biological activities for designation of novel supplementary food products in the future.

Recent research shows variations in pollen chemical constituents and, consequently, in their therapeutic properties. Mono and multifloral bee pollen extracts were investigated for antioxidant and enzyme inhibitory activity properties, phenolic compounds and fatty acid composition. Generally, Eucalyptus spp. and multifloral extracts exhibited potent inhibitory activity against α-amylase, acetylcholinesterase, tyrosinase, lipoxygenase, lipase and hyaluronidase. On the other hand, Miconia spp. demonstrated higher antihemolytic activity. Cocos nucifera and Miconia spp. extracts exhibited important antioxidant properties in the different assays (ABTS, DPPH, β-carotene/linoleic acid and reducing power). Moreover, these extracts had greater amounts of total phenols and flavonoids in comparison to others. The increase in antioxidant activity (decrease in EC50 values) was accompanied by an increase in the amount of total phenols in the extracts. The pollen extracts contained linoleic acid and α-linolenic acid as major fatty acids, followed by palmitic acid, and oleic acid. In this study, differences were observed in both chemical constituents and biological activities of the samples related to the geographical and botanical origin of bee pollen.
