The effect of adding bee pollen in beef burger on the oxidative stability was investigated. Antioxidant properties, chemical composition and vitamins were also determined. The antioxidant activity of bee pollen by DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging and β-carotene-linoleic acid methods were high. The predominant minerals in bee pollen were Mg, followed by Ca, K and Mn. Bee pollen can be considered a rich source of B6 vitamin (4.96 mg/100 g bee pollen) and the concentrations of vitamin B1 and B2 were 0.74 mg/100 g and 0.78 mg/100 g, respectively. Regarding lipid oxidation of beef burgers, assessed by thiobarbituric acid reactive substances (TBARS), it value increased at 2.09 mg malondialdehyde /kg of beef burger after 42 days storage at -12 °C. Beef burgers containing bee pollen extract inhibited 31.78 % of lipid oxidation at the end of the experiment. Thus, the strong anti-oxidative effect and high nutritive value of bee pollen suggests its potential application as natural antioxidant in meat products.

Aim: This study investigated the chemical composition, antioxidant activity, and diuretic effect of Moroccan aqueous extract of fresh bee pollen (AEFBP) in normal rats. Materials and Methods: The chemical composition of the extracted bioactive compounds was assessed using liquid chromatography with diode array detection coupled to electrospray ionization (ESI) tandem mass spectrometry (LC/DAD/ ESI-MSn). 2,2-diphenyl-1-picrylhydrazyl and the reducing power were used to assess the antioxidant properties of the extract, together with the determination of total phenols and flavonoids. To assess the diuretic effect, 20 normal rats were divided into five groups: The first was a control group administered by distilled water (10 mL/kg body weight), the second group received furosemide (10 mg/kg body weight), the third group received 100 mg/kg body weight of AEFBP, the fourth group received 250 mg/kg body weight of AEFBP, and the fifth group received 500 mg/kg body weight of AEFBP for 30 days. Toward the end of this experiment, urine output was measured, and plasma and urine were sampled to analyze creatinine, potassium, chloride, and sodium levels. Results: N1,N5,N10-tri-p-coumaroylspermidine is a spermidine derivative and was the main compound in this sample, in a total of 19 compounds identified, including flavonoids, glucoside flavonoids, and methylated derivatives. Force feeding with the AEFBP induced a significant increase in urine output and urinary electrolyte levels with a dependent dose-effect without changes in plasma electrolytes, whereas furosemide decreased plasma potassium. Conclusion: Moroccan fresh bee pollen extract contains flavonols and spermidines that induce a potential antioxidant activity related to significant diuretic effect without changes in plasma composition.

Bee pollen has been used as a food supplement and as a traditional medicine for thousands of years. Our study demonstrated that by in vitro sister chromatid exchange assay, Mimosa pudica crude bee pollen extract (0.005-5.0 μg/mL CE) from Chiangmai, Northern Thailand, increased genotoxicity in human lymphocytes at concentrations of 0.005 and 0.5 μg/mL by 20% and 24% respectively, compared to the RPMI control. Its defatted extract (DE) at 0.005-5.0 μg/mL increased the activities by 24–32% whereas the lipid extract (LE) at 0.00125 μg/mL but not at 0.0125–1.25 μg/mL increased the activities by 25%. Only CE at 5.0 μg/mL induced cytotoxicity. Pretreatments of CE, DE, and LE at 0.5, 5, and 0.00125 μg/mL induced antigenotoxicities against doxorubicin, a potent genotoxic chemotherapeutic agent by 24%, 28%, and 16%, respectively. Their protective mechanisms are feasibly involved with α-tocopherol and phenolic contents such as gallic acid and ferulic acid.

Abstract In a nanobiotechnology world with many applications in biomedicine, a novel combination of inorganic-organic materials is needed to prove a novel functionality. Natural compounds from bee pollen extract coated on magnetite nanoparticles could open up a new way in apitherapy field. Iron oxide nanoparticles have proved special requirements for biological applications like superparamagnetic properties, high biocompatibility and nontoxic material. Magnetite nanoparticles functionalized with natural bioactive substances extracted from bee pollen have been characterised and investigated for antimicrobial activity. Previous findings demonstrate that magnetite nanoparticles (MNPs) and pollen ethanolic extracts (PEE) exhibited antimicrobial activity against a large antimicrobial spectrum, including Grampositive, Gram-negative and antifungal microorganisms.
