Sažetak
The phenolic compounds of red wines are substances which play an crucial role in several sensory properties such as colour, flavour, astringency and hardness. They manifest a wide range of beneficial effects including anti-carcinogenic, anti-inflammatory and antiviral activities. These protective effects derived from the consumption of wines have been attributed to the antioxidant character of phenolics. Polyphenolic composition in wine depends on grape variety, climatic conditions, viticulture practice and vinification techniques. The main objective of the presented study was comparative analysis of wines from Armenian and Croatian local grape cultivars in order to determine their total phenolic content and total antioxidant activity. Total antioxidant activity was determined by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and 2, 2'- azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS∙+) radical cation decolourisation. They were correlated and exhibited a strong correlation (p < 0.01) with the total phenolic content determined by Folin-Ciocalteu’s reagent using gallic acid as a standard. The obtained results have confirmed a variation in the phenolic content amongst Armenian and Croatian red wines and also amongst wines made from grapes of different geographical origin. This preliminary study contributes new knowledge of the composition of the wines of different grapes and origin. Further studies are necessary to confirm the observed differences.
