Abstract

Ziziphus spina christi  and Ficus carica are known for their activities and use in traditional medicine in treating many diseases besides being nutritious and healthy for eating.  This study evaluated antioxidant activity in the bark and leaves, ethanoic extracts of  Ziziphus spina Christi (L.) and the aqueous extract of Ficus carica. The extract’s antioxidant activity was measured based on the scavenging activities of the established 1,1-diphenyl-2-picrylhydrazyl free radical scavenging method. The total antioxidant activity was measured   using Total Antioxidant Capacity Reagent (TCA), using a UV- spectrophotometer against a blank, At the same time, the standard was a series of Ascorbic Acid solutions. The results revealed that the leaves extract of sider and f. carica has total antioxidant activity less than the sidr bark extract which was 300, 40 and   700 respectively. IC50 of fig leaves extract was 260.228 µg/ml and of sider leaves and bark extract were 124.433 & 1.7924 µg/ml respectively while it was 50.558 µg/ml for ascorbic acid. The low concentration of sider park has more antioxidants activity comparing with leaves from both sider and fig.
