Physicochemical and microbiological characterization, and evaluation of the antimicrobial and antioxidant activity of propolis produced in two seasons and two areas of the eastern edge of the Sonoran Desert
This research determined the effects of season and collection location on the physicochemical quality (instrumental color and proximal chemical analysis) and microbiological properties (mesophilic, psychrotrophic, and Staphylococcus aureus counts) of raw propolis, and the biological activity of prop...

The total phenolic compounds (TPC) and total flavonoid content (TFC) were measured, and antioxidant activity was evaluated by the free-radical scavenging activity (FRSA) and reducing power ability (RPA). The antibacterial activity was determined against Gram-positive (S. aureus and Listeria monocytogenes) and Gram-negative bacteria (Escherichia coli and Salmonella typhimurium). The results showed that the physicochemical and microbiological properties of raw propolis complied with international quality standards. Propolis extracts collected during summer had the greatest effect against S. aureus, and the highest FRSA and RPA, likely because of also possessing the highest TPC and TFC among the extracts. In conclusion, the season and collection location affect the physicochemical properties of propolis, as well as the bioactivity of its extracts. Esta investigación determinó los efectos de la estación y el área de colecta sobre la calidad fisicoquímica y microbiológica del propóleos crudo, y la actividad biológica de los extractos de propóleos. El contenido de compuestos fenólicos totales (CFT) y de flavonoides totales (CFvT) fue medido en los extractos de propóleos; así como la actividad antioxidante, mediante la actividad de eliminación de radicales libres (AERL) y la habilidad de poder reductor (HPR). La actividad antibacteriana se determinó contra bacterias Gram-positivas (Staphylococcus aureus y Listeria monocytogenes) y Gramnegativas (Escherichia coli y Salmonella typhimurium). Los resultados mostraron que la estación afecta las propiedades fisicoquímicas, sin encontrarse diferencias en los recuentos microbianos del propóleos crudo. Los extractos recolectados en ambas regiones durante el verano tuvieron el mayor efecto contra S. aureus (>17 mm de zona de inhibición). Además, los extractos de propóleos de la zona 2 y recolectados durante el verano mostraron el mayor CFT and CFvT (>150 y 250 mg/g, respectivamente), así como la más alta AERL (>70% de inhibición de radicales libres) y HPR (>0.2 abs). En conclusión, la estación y área de colecta afectan las propiedades fisicoquímicas y bioactividad de los extractos de propóleos.
