title: [Antibacterial activity of polyphenolic compounds isolated from plants of Geraniaceae and Rosaceae families].
abstract: Polyphenolic compounds present in extracts of plants belonging to the families Geraniaceae (blood-red cranesbill, wood cranesbill, meadow cranesbill, and alfilaria) and Rosaceae (red raspberry, European dewberry, and tormentil) have been tested for their activity against gram-positive and gram-negative bacteria of the genera Azotobacter, Bacillus, and Pseudomonas. The bacteriostatic activity exhibited some species-related features and depended on the polarity of the extracting agent. The bacteriostatic activity of plant-derived phenolic compounds correlated with their antioxidant potential. The plants of the families Geraniaceae and Rosaceae offer promise as a source of raw material for isolation of polyphenolic compounds exhibiting bactericidal activity, including against opportunistic pathogens (B. cereus, E. coli, P. aeruginosa, and S. aureus strains).
