Antimicrobial effects of fruit and flower anthocyanins

• Our research suggest that anthocyanins are promising anti-bacterial agents
• The antimicrobial effects are highly dependent on the source of the anthocyanin-extract
• Rose-anthocyanins appear to posses the strongest anti-bacterial effects
• Gram-positive strains appear to be more sensitive compared to gram-negative strains
• Future research efforts should focus on different anthocyanin entities
