| 摘 要： | 以5 个新西兰主栽费约果品种为试材，比较不同费约果品种果实多酚类物质含量和抗氧化能力的差异。结果表明：费约果果实富含多酚类物质，特别是原花青素，且具有较强的抗氧化能力。不同基因型和果实不同部分（果皮、果肉和果浆）总酚、总黄酮、原花青素含量和抗氧化能力均有显著差异。在5 个品种中，“Anatoki”具有最高的总酚、总黄酮、原花青素含量和铁离子还原能力，且费约果果实的果皮积累总酚、总黄酮和原花青素最多，其次是果肉，果浆含量最少。

| Abstract: | Fruits from five feijoa varieties were investigated for differences in polyphenolic compounds and antioxidant
activity. The results showed that feijoa fruits contained abundant phenolics, especially proanthocyanidins, and displayed
high ferric reducing ability. Significant differences were noticed among varieties and among fruit organs. Among 5 varieties,
‘Anatoki’ had the highest contents of total phenolics, total flavonoids, proanthocyanidins and ferric reducing ability. Among
different fruit organs, skin accumulated the highest total phenols, total flavonoids and proanthocyanidins, followed in order
by cortex and locule. |
