Consumption of fruit which is rich in phenolic compounds and has high antioxidant activity, prevents risk factors of various diseases. Numerous researches confirm that plants rich in such substances reduce the risks of cancer, heart diseases and hypertension. In view of the above, the goal of the research is to study prospective peach varieties in Georgia and compare them in terms of their total polyphenols content and antioxidant activity, determine the correlation between total polyphenols content and antioxidant activity during the storage of fruits. We have studied the total polyphenols content and antioxidant activity in peach fruit of different varieties before and during the storage. The conducted research showed a strong positive correlation between total polyphenols and antioxidant activity. During the storage the total polyphenols and antioxidant activity have decreased in peaches of both varieties. This change can be generalized and considered a common pattern. However, the genotype of a variety affects the strength of correlation.
