Abstract
Introduction:
Fruits of oleaster (Elaeagnus angustifolia L.) were used in traditional
medicine to treat various diseases. The aim of this study was to
evaluate and compare the phenol and flavonoid contents and antioxidant
activity of methanol extracts from the fruit peel, flesh and seed of
seven genotypes of oleaster.
Methods:
The phenol and flavonoid contents were determined using
spectrophotometric methods. Antioxidant and antiradical activities were
determined using reducing power, ferric-reducing antioxidant potential
(FRAP) and ability to scavenge DPPH radical assays.
Results:
Significant differences (P ˂ 0.05) were found in phenol and flavonoid
contents and antioxidant activity among components of fruit and between
various genotypes.
Conclusion:
Results indicated that oleaster has good fruit quality varying among
different genotypes. Seeds of fruits have excellent antioxidant activity
and phenolic contents in comparison to flesh and peel.
