Brazilian Propolis Effective Against Oral Pathogens

Susceptibility of Oral Pathogenic Bacteria and Fungi to Brazilian Green Propolis Extract
Pharmacologyonline, 3: 467-473 (2006) de Paula et al. 467

Abstract: The aim of this study was to investigate the antimicrobial activity of ethanolic extract and fractions of Brazilian green propolis (BGP) collected by bees from Baccharis dracunculifolia against 16 oral pathogenic microorganisms. BGP was examinated by Reversed-Phase High-Performance Liquid Chromatography (RPHPLC) and its absorption spectra was assessed using UV-Spectrophotometer…

The results indicate that all microorganisms tested were susceptible to BGP. None of the essayed fractions (Coumaric acid, Kaempferol, Pinobanskin-3-acetate, Chrysin, Galangin, Kaempferide, and Artepillin C) was more active than the extract, suggesting a synergistic effect of propolis constituents for the antimicrobial activity.
