| Summary: | Fruits have been very essential in the growth and development of human life. Therefore, the present study was designed to evaluate the chemical composition of cherry, plum and pear cultivars grown in northeastern part of Hungary. Twelve fruit species were screened for their total phenolic content, antioxidant capacity and mineral content. The results show that the chemical composition and antioxidant capacity of the investigated fruits varies significantly. Total phenolic contents of the selected fruit cultivars (cherries, plums and pears) were investigated according to the method of Singleton and Rossi, while the antioxidant activity of the fruits was determined using the ferric reducing antioxidant power (FRAP) assay. Positive correlation was found between the total phenolic content and antioxidant activity that means the phenolic content of these fruits contributes to antioxidant capacity. Mineral contents varied greatly between the species. Cherry was found to be the richest source of minerals. The most abundant mineral detected was potassium, followed by calcium and phosphorus. The trace elements were detected in lower amounts. Results showed that these fruits contain considerable amounts of minerals and phenolics, resulting also in significant antioxidant activity. They strongly support the evidences that fruits promote health benefits. These fruits, especially cherries could be potential rich resources of natural antioxidants and could be developed into functional foods or drug for the prevention and treatment of diseases caused by oxidative stress. |
