In this study, we assessed the therapeutic potential of propolis from Poland and performed chemical analysis by GC-MS, as well as determined its botanical origin. Chemical constituents typical for bud exudates of Populusnigra (section Aigeiros) were determined, however, glycerol esters of phenolic acids, as well as unusually high amounts of p-coumaric and ferulic acid and their benzyl esters, w...

The Roman scholar Plinius (23-79 A.D) postulated, that it originates in the buds of different trees like willow, poplar, elm, reed and other plants. He knew of the use of propolis as a glue in the hive and about its medicinal properties and described them in his 35 volumes Natural History. He says “Current physicians use propolis as a medicine because it extracts stings and all substances embed...

propolis, a resinous substance collected by apis mellifera bees from various plant sources is transformed in the presence of bee enzymes. short- and long-term effects of diet supplementation with ethanol extract of iranian propolis (eeip) was investigated on growth and immunity in juvenile rainbow trout. the fish (mean body weight 30 ± 3.2 g) were fed a commercial diet supplemented with 0 (cont...

BACKGROUND Propolis has been used worldwide as a dietary supplement to maintain and improve human health. We examined whether ethanol extracts of Brazilian propolis exhibit antiviral activity against influenza virus in vitro and in vivo. METHODS Among 13 ethanol extracts screened in a plaque reduction assay, four showed anti-influenza virus activity. The anti-influenza efficacy of the four ex...

Among a long list of parasites and pathogens that threaten the European honey bee (Apis mellifera), Foulbrood (EFB) has become an urgent apiary disease, as epidemic outbreaks are becoming increasingly common. EFB is bacterial disease larval bees, caused by gram-positive, anaerobic bacterium, Melissococcus plutonius. The most effective current treatment for EFB, oxytetracycline hydrochloride, ca...

BACKGROUND Bee propolis, a mixture of the secretion from bee tongue gland and wax gland, was collected from the tree bud and barked by bees. The components were rich in terpenes, phenolics, and flavonoids, and had anti-cancer, anti-bacterial, anti-inflammatory, hepatoprotective, and neuroprotection abilities. However, the potential anti-oxidative stress of propolis was not well documented. This...

INTRODUCTION Propolis is a sticky material mixed by honeybees to utilize it in protecting their hives from infection by bacteria and fungi. The therapeutic properties of propolis are due to its chemical composition with bio-active compounds; therefore, researchers are interested in studying its chemical constituents and biological properties. The main objective of this study is to determine the...

The present study is aimed to evaluate the chemical characterization and antimutagenic potential of propolis extracted in three different solvents (ethanol, polyethylene glycol water). properties extracts were identified using HPLC-DAD LC?MS/MS extract found be richer than ethanolic water considering composition. In addition, activities determined Ames assay. concentrations 3, 1.5 0.75 mg plate...

Propolis produced by selected bees Apis mellifera were collected from March to June of 2013 and in March of 2015 and analyzed in order to evaluate the in uence of climate, colony of origin, and food supplementation of colonies on the content of total phenolic and avonoid by chromatographic analysis and antioxidant activity by radical scavenging of 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) an...
