Propolis is the resinous material that bees gather from leaf buds, flowers and vegetables. Propolis extracts contain constituents with a broad spectra of pharmacological properties and are important ingredients of popular dietary supplements. Propolis extracts were evaluated in vitro for inhibition of recombinant human monoamine oxidase (MAO)-A and MAO-B. The dichloromethane extract of propolis...

Ethanol and dichloromethane extracts of a Brazilian green propolis from Baccharis dracunculifolia were analyzed by HPLC-APCI-MS and GC-MS, respectively. The HPLCAPCI-MS technique, at the positive mode, furnished a complete and unequivocal chemical composition of the green propolis sample. It serves as fi ngerprint for different propolis samples. The composition of the ethanol extract consisted ...

Brazilian green propolis is a resinous substance prepared by bees from parts of the plant Baccharis dracunculifolia. As it possess several biological properties, this work assessed the cytotoxic/anticytotoxic, genotoxic/antigenotoxic and mutagenic/antimutagenic potential of ethanolic extracts of Brazilian green propolis (EEGP) and of B. dracunculifolia (EEBD), by means of the Allium cepa test s...

Propolis obtained from bee hives is a natural substance with antimicrobial properties. It is limited by its insolubility in aqueous solutions; hence ethanol and ethyl acetate extracts of Malaysian propolis were prepared. Both the extracts displayed antimicrobial and anti-biofilm properties against Enterococcus faecalis, a common bacterium associated with hospital-acquired infections. High perfo...

The antibacterial activities of propolis samples have been examined in vitro, according to the principles accepted for the determination of a similar activity of antibiotics with the use of solid and liquid media. It has been found that propolis extracts showed antibacterial activity through a range of commonly encountered gram positive cocci (S. aureus, beta hem. Streptococus), but had weak ac...

Different products from a unique propolis extract obtained by using various solvents such as hydroalcoholic, glycolic (98% propylene glycol), and glyceric solutions, and oil, as well as in powder form, named ESIT12, were prepared. The molecular composition of the different preparations was evaluated and their antioxidant activity determined. All the preparations showed a quite similar polypheno...

A simplex-lattice mixture design with response surface methodology was used to evaluate in vitro synergistic antioxidant activity of red, green, and brown Brazilian propolis extract blends. The capacity blends measured using the fluorine method oxygen radical absorption assay (ORAC assay). interaction identified between green extracts, predictive model accused a binary composed 59% 41% extracts...

OBJECTIVE To evaluate the healing action of green and red propolis, correlating it with the content of flavonoids. METHODS We performed quantification of total flavonoids of green and red propolis ethanol extracts for subsequent incorporation in ointment base to 20%. We used 20 Wistar rats divided into four groups: 0.9% saline (S), ointment base (B), green propolis ointment (G) and red propol...

BACKGROUND To evaluate and compare the effects of ethanolic extracts of Malaysian propolis and Brazilian red propolis at different concentrations on the migration and proliferation of fibroblast cells. METHODS Malaysian and Brazilian red propolis crude samples were extracted using ethanol. Their wound healing effects were tested in vitro on the normal human fibroblast cell line CRL-7522. Cell...

Propolis is a natural resinous substance (bee glue) collected by honey bees. The aim of the study was to perform phytochemical analysis of different extracts of propolis viz. ethanolic extract, methanolic extract and water extract. The antibacterial activity was studied by using Well diffusion method and Macro Broth dilution method against Salmonella typhimurium at different concentration like ...
