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.

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.

Generation of reactive oxygen species (ROS) is associated with dysregulation of antioxidant defense mechanisms and incidence of human diseases. The specific aim of this study was to investigate the lipid oxidation and antioxidant activity of aqueous extract of Rheum officinale Baillon rhizome in order to evaluate its potential as a future novel natural antioxidant resource and a functional ingredient in food and pharmaceutical formations. Total phenolic and flavonoid contents of Rheum rhizome extract were dose dependently increased. Consistent with this, radical scavenging activities of Rheum rhizome extract as determined by 2,2-diphenyl-1-picrylhydrazyl assay and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity were significantly elevated as the concentration increased. In addition, the treatment of aqueous Rheum rhizome extract significantly increased ferric reducing and copper chelating activities. According to results of thiobarbituric acid reactive substance analysis, Rheum rhizome extract significantly delayed lipid oxidation. Preincubation with Rheum rhizome extract significantly inhibited tert-butyl hydroperoxide- (t-BHP-) induced ROS generation. Moreover, superoxide anion production was significantly lower in Rheum rhizome extract-treated RAW264.7 macrophage cells than t-BHP-incubated cells (p<0.05). These findings suggest that Rheum officinale Baillon rhizome extract has a potential as an excellent natural antioxidant agent.

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.
