Among the samples analyzed, the pepper populations exhibited the highest concentration of vitamin C, measured at 51.25 mg/100g. Conversely, the lowest levels of vitamin C were observed in apples and grapes, approximately 9 mg/100g. When considering the overall antioxidant activity, tomatoes and peppers displayed the largest proportion of vitamin C, accounting for over 75 mg/100g. Furthermore, the highest quantity of anthocyanins was found in cherries, specifically 394.30 mg/kg FW (FW = Fresh Weight). Pomegranate varieties exhibited the greatest content of total phenols, measuring 5359.43 mg/kg FW, along with the highest fruit antioxidant activity, showing 81.58 % inhibition. As for apple varieties, they contained the highest amount of flavan-3-ols, reaching 517.98 mg/kg FW. Our analysis revealed a positive correlation between total phenols and antioxidant activity, as well as between total phenols and flavan-3-ols. Additionally, a moderate negative correlation was identified between vitamin C and flavan-3-ols. | Опис: | / | URI: | http://hdl.handle.net/20.500.12188/31752 |
