Propolis is one of the most fascinating honey bee (Apis mellifera L.) products. It a plant derived product that bees produce from resins they collect different organs and with which mix beeswax. building material protective agent in hive. also plays an important role social immunity, widely used by humans as ingredient nutraceuticals, over-the-counter preparations cosmetics. Its chemical composition varies geographic location, climatic zone local flora. The understanding diversity propolis...
Context: Traditionally, the content of total phenolics (flavonoid (FP) and non-flavonoid (NFP)) flavonoids (flavone/flavonol flavonone/dihydroflavonol) in propolis has been determined by different methodologies. Until now, percentage phenolic (TP) compounds that corresponds to FP NFP, expressed same units a spectrophotometric method, not determined.
The effect of seasonality on Argentine propolis collected during one year its phenolic and flavonoid content the growth Gram-positive Gram-negative antibiotic resistant bacteria Candida species was evaluated. Extracts samples in summer spring showed higher contents than other seasons (5.86 to 6.06 mg GAE/mL 3.77 4.23 QE/mL, respectively). autumn antibacterial activity (30 microg/mL) (MIC values between 30 120 microg/mL). No detected against bacteria. Also, these extracts were able inhibit...
Propolis production by honey bees is the result of a selective harvest exudates from plants in neighborhood hive. This product used Argentina as food supplement and alternative medicine. The aim this study was to determine botanical origin propolis arid regions Monte using rapid histochemical techniques comparison TLC HPLC-DAD chromatographic profiles with extract obtained Zuccagnia punctata, Larrea divaricata cuneifolia, plant species that grow area natural community named "jarillal"....
Abstract The effect of Argentine propolis extracts against enzymes related to metabolic syndrome and oxidative stress, as well the botanical origin raw propolis, were studied. Histological chemical analyses samples revealed that is Zuccagnia punctata , an medicinal plant. melissopalynological analysis showed both pollen grains Z. other plant species. This result indicates differences found in remains compared palynological studies may have been caused by bees selecting resinous shrubs mainly...
Propolis has been used in ethnobotany and traditional practices is currently considered a source of phytotherapeutics. The aim this study was to develop an antibiotic antioxidant hydrogel containing Argentine propolis extract evaluate its stability for one year different conditions. A fingerprint by HPLC-DAD showed the presence caffeic, coumaric, ferulic cinnamic acids, caffeic acid phenethyl ester (CAPE) flavonoids such as pinobanksin, apigenin, kaempferol, pinocembrin, chrysin, galangin....
Propolis with a botanic origin in Zuccagnia punctata Cav. (Fabaceae), plant species widely distributed the Argentinean Monte region, was used to produce standardized propolis extract by biological activity and chemical composition. In this paper effect on microorganisms isolated from otitis determined. The active against different Staphylococcus strains MIC MBC values (75 150 μg DE/mL, 200 600 respectively) of 800 DE/mL Proteus mirabilis. A pharmaceutical product, ear drops containing as...
