Berries fruits contain many different chemical compounds with different biological and pharmacological capacities and properties. So, these fruits are a source of bioactive molecules with antioxidant activity such as phenolic compounds, flavonoids, anthocyanins, ascorbic acid, that are important to human nutrition. Antioxidants neutralize free radicals, which cause oxidative damage to lipids, proteins, and nucleic acids and thus protect the organism. Research studies carried out on this topic indicated that natural antioxidants are involved in protection against many deseases: cancer, cardiovascular deseases, osteoporosis. The objective of this research was to determine and compare the antioxidants content offered by six berries fruits species: raspberry (Rubus idaeus), blackberry (Rubus fructicosus), strawberry (Fragaria ananassa), chokeberry (Aronia melanocarpa), blackcurrant (Ribes nigrum), sea-buckthorn (Hippophaea rhamnoides). The evaluation involved determination of total phenols, anthocyanins and flavonoids, using spectrophotometrical methods. Higher total phenol content levels were obtained in chokeberries and in blackcurrants.
