摘要: 以那翁、拉宾斯、佐藤锦、雷尼和红灯为试材,测定果实色度和抗氧化物质含量(总酚、总黄酮、总黄烷醇),并采用3种机制(DPPH、ABTS和FRAP值)综合评价它们的抗氧化活性。结果表明,不同甜樱桃品种的色度、抗氧化物质含量和抗氧化活性存在差异。红肉品种红灯和拉宾斯的a*值最大,b*值很低,而黄肉品种恰好相反,那翁亮度值L*最高。红灯抗氧化物质成分总酚和总黄酮含量最高。不同方法检测的抗氧化能力也是红灯最高,拉宾斯次之,而黄肉品种佐藤锦和那翁的抗氧化能力最低。相关性分析表明,总酚、总黄酮和抗氧化能力间均呈极显著或显著正相关关系,而总黄烷醇只跟总抗氧化能力检测法(ABTS)呈显著相关关系。因此,红肉甜樱桃可作为抗氧化物质的重要来源,其中红灯具有良好的发展价值和保健功能。

Abstract: To investigate the International Commission on Illumination (CIE) values and antioxidant capacity of different varieties of sweet cherry fruit, Napoleon, Lapins, Sato Nishiki, Rainier, Hongdeng were used as materials to determine the content of the 3 antioxidants (total phenolics, total flavonoids and total flavanols).The antioxidant activities of 3 different mechanisms were evaluated in terms of the antioxidant activity of sweet cherry fruits, including ABTS.+ radical scavenging capacity (ABTS), DPPH radical scavenging capacity (DPPH), and iron ion reducing ability (FRAP).The results showed that differences were found among different varieties. Red-fleshed sweet cherry varieties Hongdeng and Lapins owned higher a* value and lower b* value, while the yellow-fleshed varieties were on the contrary, and Napoleon had the highest L* value. Hongdeng had the highest content of antioxidant compounds and also had the highest antioxidant capacity, while the yellow-fleshed varieties Sato Nishiki and Napoleon were the lowest. Moreover, significant or extremely significant positive correlations were found between total phenolics (TPC), total flavonoids (TFC) and each bioactive compound, and significant positive correlation was found between total flavanols (TFAC) and ABTS. All of these results suggested that red-fleshed sweet cherries contained high antioxidants, and Hongdeng is a promising hygienical function for human nutrition.
