Sažetak:
The aim of the present study was to determine polyphenolic composition, related antioxidative and antimicrobial properties of grape skin extracts from 14 grape varieties (7 white and 7 red grape) grown in Dalmatia (Croatia). The content of total phenols, flavonoids, catechins, flavanols and individual polyphenols: (+)-catechin, (-)-epicatechin, epicatechin gallate, procyanidin B1 and procyanidin B2, quercetin glucoside, resveratrol monomers, piceid and astringin, was variety dependent. Antioxidant properties were determined as a DPPH radical scavenging ability (IC50), ferric reducing/antioxidant power (FRAP), Fe2+ chelating activity (IC50), and using β -carotene bleaching assay. The high antioxidant capacity of all extracts, both red and white, has been observed and related to the relative amounts of polyphenolic compounds with good antioxidant properties. The antimicrobial activity was screened by broth microdilution test using gram-positive (Stapylococcus aureus, Bacillus cereus) and gram-negative bacteria (Escherichia coli O157:H7, Salmonella Infantis, Campylobacter coli). It was confirmed against all tested organisms. Minimum inhibitory concentrations (MICs), were found in the range 0.014 – 0.59 mg of gallic acid equivalents (GAE)/mL, but in average with lower MICs of white cultivars, especially against Campylobacter and Salmonella.
