Abstract
Plant polyphenols are structurally diverse compounds that have been used medicinally for centuries due to their antimicrobial properties.
In the current study forest fruit extracts and red wine samples were subjected to hydroalcoholic extraction and concentration by rotoevaporation. pH, total polyphenol concentration were monitored whit antimicrobial specific action tested on E. coli, Klebssiella, S. aureus bacterial cultures.
Total polyphenol concentrations reached 2,450 g L-1 with minimums of 1,400 g L-1 in red wine samples and 2,332 g L-1 with a minimum of 1,089 g L-1 for fruit samples.
Fruit and wine extracts showed variable diameters of inhibition.
Only S. aureus and E. coli were sensitive to proposed studied extracts.
Results showed that polyphenols can be an alternative to conventional antibiotic therapy, confirming some indications from literature.
