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.

Key words: feijoa, fruit, polypenolic compounds, ferric reducing activity
