| Popis: | Sweet cherry fruits are readily consumed by humans, and they contain significant quantities of bioactive compounds. Fifteen sweet cherry ( Prunus avium L.) old cultivars grown in the Czech Republic were examined. In fresh fruits the contents of sugars, organic acids, and phenolic compounds, and antioxidant capacity were determined. The analyses showed that the fruits of sweet cherry are characterized by high contents of bioactive compounds. Four organic acids – malic, quinic, shikimic, and fumaric acid – were determined in examined fruits. The cultivar ‘Lyonska Rana’ was characterized by the highest total polyphenol content (202.28 mg GAE/100 g FW) and high antioxidant activity (ABTS – 2765.3 µmol TE/100 g FW, FRAP – 1663.67 µmol TE/100 g FW), with the lowest content of organic acids. The ‘Sakvicka’ cultivar was characterized by the highest content sum of sugars (16.36 g/100 g FW) and sweetness (19.08 g/100 g FW), with low contents of polyphenols and antioxidant activity. |
