In this paper the antioxidant activity of ethanolic extracts from Solanum retroflexum
Dun fruits were investigated. The extracts were obtained by classical technique and by
Soxhlet extraction. In order to investigate the possibilities of future utilization of
Solanum retroflexum fruits, the antioxidant activity, by FRAP and DPPH method was
determined. Results showed the extract obtained by 75% ethanol and classic extraction
during 45 minutes at 60°C, had the highest antioxidant activity, both for DPPH and
FRAP method (EC50 was 60,67 μg/mL and 1,55 μmol Fe2+/mg, respectively). There was
good correlation of results for antioxidant activity obtained by both methods and for all
analyzed extracts. Rad se bavi ispitivanjem antioksidativne aktivnosti etanolnih ekstrakata
ploda biljke Solanum retroflexum Dun. Ekstrakti su dobijeni tehnikama klasične i
Soxhlet extrakcije. Potencijalna antioksidativna aktivnost je ispitana FRAP i DPPH
metodama. Rezultati su pokazali da ekstrakt dobijen klasičnom ekstrakcijom sa 75%
rastvorom etanola na 60°C i za vreme 45 minuta, ima najveću antioksidativnu aktivnost
(EC50 = 60,67 μg/ml, 1,55 μmol Fe2+/mg), kao i da postoji dobra korelacija rezultata
dobijenih obema metodama u slučaju svih analiziranih ekstrakata.
