Antioxidants in different parts of oleaster as a function of genotype.

Faramarz S, Dehghan G, Jahanban-Esfahlan A - Bioimpacts (2015)

Bottom Line: 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.Significant differences ( P < 0.05) were found in phenol and flavonoid contents and antioxidant activity among components of fruit and within various genotypes.

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 within 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.

Mentions: The FRAP assay showed greater variability among various extracts. These differences in antioxidant activities among oleaster peel, flesh and seed are shown in Fig. 4. Methanol extract of seed was significantly more active than all other components (P < 0.05). These activities also were different among the oleaster genotypes. The highest FRAP value in the oleaster seeds was 0.80 ± 0.14 mM Fe2+/mg Ext for IEa-3 and the lowest FRAP value, 0.17 ± 0.02 mM Fe2+/mg Ext, was obtained for IEa-2. The maximum FRAP value in flesh extracts was 0.39 ± 0.062 mM Fe2+/mg Ext for Ea-1 and the lowest, 0.04 ± 0.003 mM Fe2+/mg Ext, was obtained for IEa-4. The maximum FRAP value in peel extracts was 0.2 ± 0.019 mM Fe2+/mg Ext for IEa-5 and the lowest of it,0.09 ± 0.014 mM Fe2+/mg Ext was obtained for IEa-6.
