|b In this study three samples of oleo-gum resins of Boswellia papyrifera (Tarak tarak) grown in some parts of the Sudan were used (Kordofan, Damazine and Nagawa). Extracts, acid fractions and essential oils of the three samples were subjected to screening for evaluating their antioxidant activity via the 2, 2-diphenyl-1 picrylhydrazyl (DPPH) and iron chelating potential (ICP) assays. All examined materials showed antioxidant activity towards DPPH radical in dose dependent manner. Treatment at 30 minutes resulted in poor DPPH radical scavenging activity compared to 60 minutes. At the highest concentration, 100μg/μL, the essential oils of the three samples showed the uppermost activities of 42.25- 51.38% and 41.76- 45.94% at 60 and 30 min, respectively. The three investigated samples showed considerable iron chelating potentials. For Kordofan and Nagawa samples, ICP increased with coincident increased concentrations. At concentration of 1.00 μg /μL petroleum ether extracts gave the highest ICP (90.05%- 93.15%), with IC50 of 0. 27- 0.34 μg /μL. The study concluded that essential oils and various extracts of Sudanese B. papyrifera can be of potential use as natural antioxidants in food and pharmaceutical industries.
