Phenol composition, radical scavenging activity and antimicrobial activity of berry leaf extracts 2016 http://ezaposleni.singidunum.ac.rs/rest/sciNaucniRezultati/oai/record/2/9922 http://www.bcc.bas.bg/index.html A. Milenković Anđelković M. Anđelković A. Radovanović B. Radovanović V. Ranđelović Berry leaves are recognized as potential medicaments which are rich in different phenolic compounds, and have been used in folk medicine for centuries. In order to evaluate phenol composition, berry leaf extracts were subjected to spectrophotometric and HPLC analysis. The radical scavenging activity was estimated using the DPPH test and the antimicrobial activity by the microwell dilution test. All extracts showed high phenol content but different compositions of phenol compounds. Flavonols, flavan-3-ols and phenolic acids were the main phenol classes found in the investigated leaf extracts. All extracts showed significant radical scavenging activity correlating with the total phenol content. Significant antimicrobial activity was found against Gram-positive, followed by Gram-negative strains, and yeast in all tested leaf extracts. All berry leaf extracts, rich in phenolic content, with significant antiradical and antimicrobial activity, can be used as food and medical supplements. article 48 1 27 32 0324-1130 Bulgarian Chemical Communications
