Bioactive content and antioxidant characteristics of wild (Fragaria vesca L.) and cultivated strawberry (Fragaria × ananassa Duch.) fruits from Turkey

In this study, some biochemical (total soluble solid content, pH, acidity and vitamin C) and in vitro antioxidant activity, total phenolic content, total ellagic acid and concentration of anthocyanins of fifteen wild strawberry genotypes ( Fragaria vesca L.) and one commercial strawberry cultivar Camarosa ( Fragaria × ananassa Duch.) sampled in Northeastern Turkey were determined. Antioxidant activity of fruit samples was determined by DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (Ferric reducing antioxidant power) assays. Notable differences were found both among wild strawberries and also between wild strawberries and cv. Camarosa. Among the strawberry accessions tested, the total phenolics ranged from 138 mg to 228 mg gallic acid equivalent per 100 g fresh fruit. The total monomeric anthocyanin content was the highest in wild genotype FV-2 (53.51 mg/100 g) while the lowest in FV-6 as 25.11 mg per 100 g fresh weight basis. The total ellagic acid content was between 15.18 and 26.36 mg per 100 g. All wild strawberries had higher antioxidant activity than cv. Camarosa. Thus, it can be concluded that wild strawberry is a good source of polyphenols, ellagic acid and antioxidants.
