Antioxidant Properties of Water Extracts for the Iraqi Plants Phoenix Dactylifera, Loranthus Europeas, Zingiber Officinalis and Citrus Aurantifolia

Abstract

In the present study, the antioxidant activities (%AA) of the water ext. for Phoenix dactylifera, Loranthus europeas, Zingiber officinalis, Citrus aurantifolia was measured by the TBARS method. Total phenol content, DPPH scavenger free radical activity and the iron chelation capacity of these exts. were also quantified. The results revealed that Phoenix dactylifera, Citrus aurantifolia had a significantly (P < 0.05) higher total phenol, and iron chelation ability, DPPH scavenging activity, and (%AA) than Loranthus europeas and Zingiber officinalis. Meanwhile the water exts. of Phoenix dactylifera and Citrus aurantifolia had the highest protective ability and this probably due to its higher antioxidant activity (AA%), total phenol content, iron chelation and DPPH scavenging activity.
