“…The flavonoid concentration was determined by adapting the spectrophotometric procedure described by Chaillou et al (2004) and Teles (2014). Aliquots of 0.2 mL of methanolic pulp extract (1:1) and 0.2 mL methanolic AlCl 3 solution (5% m/v) were added to a cuvette and the volume completed to 2 mL with concentrated methanol.…”

The proximate compositions, mineral contents, antioxidant capacity and bioactive compounds of 7 native Amazon fruits were chemically evaluated. The majority of the fruits showed high moisture contents (> 63.02%), and ash, total crude protein and total carbohydrate contents in the ranges of 0.22–2.07%, 0.17–2.44% and 7.17–41.71%, respectively. High levels of total lipids were found in uxi (23.25%) and monguba (18.67%). A wide range of mineral contents was detected and the highest levels were found in the samples of monguba seeds (Ca, Cu, Mg, and Zn), uxi pulp (Fe, and Mn) and pajurá pulp (Na). All the fruits showed antioxidant capacity, but the pajurá revealed the highest potential, statistically similar to that of acerola (p < 0.05). The highest vitamin C contents were found in bacuri and cupuaçu and the highest phenolic compound contents in monguba and pajurá fruits, but flavonoids were only detected in pajurá. A statistical correlation between the Na content and antioxidant capacity was also observed. Based on the results obtained, the fruits analyzed are suitable for use in the human diet, in the food and cosmetics industries as well as in pharmaceutical compositions.

“…In the hive, bees use propolis for different purposes, such as closing cracks, minimizing access routes, coating and isolating animal remains that have been introduced into the hive, consolidating structural components, varnishing the inside of the hive cells for disinfectant purposes, and avoiding vibrations (Chaillou et al, 2004).…”

Introduction: The data available regarding the chemical composition and procedures for the extraction of the propolis are currently inconclusive. In this study the chemical groups present in the extracts of a propolis mixture obtained by different methods were identified. Additionally, their content of polyphenols and flavonoids was determined, and antioxidant and antibacterial activity was studied. Method: The extracts were obtained by maceration and for the ultrasonic and microwave method. Phenolic and flavonoid compounds, as well as the measurement of antioxidant activity, were quantified by spectrophotometric methods. The antibacterial activity was studied from the inhibitory effect of each extract against Escherichia coli, Salmonella typhi, Staphylococcus aureus and Proteus mirabilis, and by the percentage of activity and the Index of Bacterial Susceptibility (IBS). Results: The phytochemical screening evidenced the presence of abundant compounds with important biological activity. It was found a significant difference (p < 0.05) in the antioxidant and antimicrobial activity of the extracts of propolis obtained by different methods. Conclusion: The presence of chemical groups of bioactive compounds and their antioxidant and antibacterial activity justifies the use of these extracts in traditional medicine.

“…) indican una actividad antibacterial del propóleo contra Enterococcus sp, Escherichia coli, y Staphylococcus aureus. Los propóleos de las abejas africanizadas presentan mayores halos de inhibición contra el S. aureus que los de abejas europeas ( Moura et al, 1999); en propóleos argentinos, 50 % de las muestras inhibieron en más de 12 mm cepas de S. aureus y el diámetro del halo de inhibición dependió del contenido de flavonoides en los extractos etanólicos del propóleo (EEP) (Chaillou et al, 2004;Lotti et al, 2010). No obstante, Manrique y Santana (2004) reportan halos de inhibición de 11 a 25 mm contra las bacterias S. aureus y Micrococcus luteus, aunque los EEP mostraron 0.19 % a 0.32 % de flavonoides y elevada actividad antioxidante.…”

ResumenSe ha evaluado la actividad antimicrobiana de los extractos etanólicos y acuosos de propóleos recolectados en la Huasteca Potosina, en México. Se usaron cepas de microorganismos Gram negativos: Escherichia coli, Salmonella typhi y Klebsiella pneumoniae; y microorganismos Gram positivos: Staphylococcus aureus, Staphylococcus epidermidis y Streptococcus agalactiae. La concentración mínima bactericida (CMB) de cada extracto se determinó con el método de dilución en tubo. La CMB del extracto etanólico fue 0.93 mg mL -1 para las Gram positivas y 7.5 mg mL -1 para las Gram negativas; en el extracto acuoso fue 20 mg mL -1 para Gram positivas y 30 mg mL -1 para Gram negativas. Los extractos etanólicos del propóleo tienen una actividad antibacteriana significativamente mayor que los extractos acuosos, y esta actividad depende de su procedencia y de la especie bacteriana evaluada. Palabras clave: propóleos, actividad antimicrobiana, microorganismos Gram, concentración bactericida Evaluation of Antimicrobial Activity of Extracts of Huasteca Potosina Propolis AbstractThe antimicrobial activity of ethanolic and aqueous extracts of propolis in the Huasteca Potosina, in Mexico was evaluated. Strains of Gram negative: Escherichia coli, Salmonella typhi and Klebsiella pneumoniae, and Gram positive microorganisms: Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus agalactiae, were used. The minimum bactericidal concentration (MBC) of each extract was determined by the tube dilution method. The ethanol extract was significantly more inhibitory than the aqueous (p ≤ 0.05). The ethanol extract CMB was 0.93 mg mL-1 for Gram-positive and 7.5 mg mL-1 for Gram negative, in the aqueous extract was 20 mg mL-1 for Gram-positive and 30 mg mL-1 for Gram negative. The ethanol extracts have higher antibacterial activity compared with aqueous extracts, and antibacterial activity depends on its origin and on the bacterial species evaluated.
