Abstract
Date seed extracts (DSE) obtained from ethanol and acetone extraction at different concentrations (0 20 40 60 80 and 100 v/v) were characterized. Yield phenolic and flavonoid contents increased as the concentration of ethanol and acetone increased up to 60 and 80 (v/v) respectively (P0.05). The highest DPPH and ABTS radicals scavenging activities and ferric reducing antioxidant power (FRAP) were observed when ethanol and acetone were used at the concentrations of 60 and 80 (v/v) were used respectively (P0.05). However the highest chelating activity was obtained when ethanol and acetone were used at a concentration of 20 and 40 (v/v) respectively (P0.05). DSE prepared using 60 (v/v) ethanol (DSE-E60) and 80 (v/v) acetone (DSE-A80) were seen to have the tannic acid contents of 16.60 and 18.15 mg/g dry solid respectively. Both extracts at levels of 100 and 200 ppm could inhibit lipid oxidation in both -carotene linoleate and fish mince model systems. Therefore it can be concluded that DSE-E60 and DSE-A80 can potentially be used as an alternative source of natural antioxidant.
