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 'Lyonská Raná' was characterized by the highest total polyphenol content (202.28mg GAE/100g FW) and high antioxidant activity (ABTS - 2765.3µmol TE/100g FW, FRAP - 1663.67µmol TE/100g FW), with the lowest content of organic acids. The 'Šakvická' cultivar was characterized by the highest content sum of sugars (16.36g/100g FW) and sweetness (19.08g/100g FW), with low contents of polyphenols and antioxidant activity.
甜樱桃果实很容易被人类食用，并且含有大量生物活性化合物。对在捷克共和国种植的15个甜樱桃（Prunus avium L.）老品种进行了检测。测定了新鲜果实中糖、有机酸、酚类化合物的含量以及抗氧化能力。分析表明，甜樱桃果实的特点是生物活性化合物含量高。在所检测的果实中测定出了四种有机酸——苹果酸、奎尼酸、莽草酸和富马酸。“Lyonská Raná”品种的总多酚含量最高（202.28毫克没食子酸当量/100克鲜重）且抗氧化活性高（ABTS——2765.3微摩尔 Trolox 当量/100克鲜重，FRAP——1663.67微摩尔 Trolox 当量/100克鲜重），但其有机酸含量最低。“Šakvická”品种的糖含量总和最高（16.36克/100克鲜重）且甜度最高（19.08克/100克鲜重），但其多酚含量和抗氧化活性较低。
