Abstract
Strawberry (Fragaria ananassa Duch.) is a good source of natural antioxidants. Fruits from eight Strawberry (Fragaria ananassa Duch.) cultivars (‘Kurdistan’, ‘Merck’, ‘Camarosa’, ‘Paros’, ‘Queen Elisa’, ‘Ventana’, ‘Selva’ and ‘Pajaro’) were harvested at ripen stage and analyzed for total phenolic content, total anthocyanin content, vitamin c, total soluble solid and total antioxidant activity. The results showed that the highest TSS was found in Kurdistan, Camarosa, Merek and Ventana cultivars. The cultivars of ‘Pajaro’, ‘Queen Elisa’ and ‘Paros’ had the lowest total phenolic contents. Total Anthocyanin and vitamin C content were highest in ‘Kurdistan’, ‘Merek’ and ‘Camarosa’. Among the investigated strawberry fruits the cultivar of ‘Merek’ showed the highest amount of total titratable acidity,  while regarding to total antioxidant activity ‘Queen Elisa’ showed lower total antioxidant activity. There were significantly positive correlation between traits of total phenolic content (0.41), total anthocyanin content (0.42), vitamin C (0.53) total titratable acidity (0.53) and total antioxidant activity. Generally, ‘Kurdistan’, ‘Merek’ and ‘Camarosa’ were good source of antioxidant compounds.
