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: One of the most significant current discussions around the world is to identify genotypes with high amounts of polyphenols for targeting enhanced performance properties in edible plants including fruits and vegetables. In this study the content of total phenolic in each genotype of oleaster peel, flesh and seed was determined spectrometrically according to the Folin-Ciocalteu method and calculated as quercetin equivalents (QE). Fig. 1 shows the total phenolic content of the seven oleaster seed, flesh and peel. Differences in phenolic content among different genotypes were statistically significant (P < 0.05). As shown in Fig. 1, E. angustifolia seed contains high amounts of phenol content as compared to the other parts of fruit in each genotype. The results imply that the methanol extract of seeds could be effective in the antioxidant and free radical scavenging activity. Total phenolic content in seed ranged from 2.14 ± 0.12 (IEa-6) to 6.26 ± 0.04 (IEa-3) mM Q/mg Ext. For flesh, it ranged from 0.14 ± 0.07 (IEa-4) to 1.54 ± 0.04 (IEa-1) mM Q/mg Ext and in peels ranged from 0.12 ± 0.05 (IEa-1) to 2.59 ± 0.15 (IEa-5) mM Q/mg Ext (Fig. 1 and Table 1).
