Introduction. The fruit types such as raspberries (Rubusidaeus), cherries (Prunus cerasus), blackberries(Rubus fructicosus), blackthorns (Prunus spinosa) andaronia (Aronia melanocarpa) are very common in Serbia. These fruitspecies are a valuable source of antioxidants. The goal of our work was to evaluate theantioxidant activities of ethyl acetate extracts of these five berries and to establishpossible correlation between the content of anthocyanin and the antioxidant activity.Materials and methods. To determine antioxidant activity of the selectedfruits, the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, the ABTS(2,2-azinobis-3 ethyl benzothiazoline-6-sulfonic acid) cation decolorization activity, theFRAP (ferric reducing antioxidant power), and the TRP (total reducing power) weremeasured. Results. The four methods selected for our assays showed strongantioxidant properties for blackberry samples. The total anthocyanin content was estimatedusing the pH differential method. The highest amount of anthocyanin was found inblackberry samples [(1063.53 ± 0.01) mg·kg–1 fresh fruit], while the lowest was inraspberry samples [(180.84 ± 0.02) mg·kg–1 fresh fruit]. The correlation between thecontent of anthocyanin and antioxidant activity was established using regression analysis.The highest correlation was found between total reducing power and total anthocyanin(r = 0.97, p < 0.05). Hierarchical cluster analysisdivided selected fruit species into two statistically significant clusters.Conclusion. Our results confirmed that analyzed berries are rich inanthocyanins. A strong correlation among different assays as well as with anthocyanincontent was observed. Cluster analysis can be used in food science, to classify differentfood types into groups, based on similarity among the results.
