Phytochemical screening of the different extracts obtained from each of Capparis spinosa L. and Capparis decidua Edgew (Forssk.) from Jordan revealed the presence of alkaloids, tannins, saponins, flavonoids, anthraquinones, and glycosides. In addition, the total phenolic content (TPC, expressed as gallic acid equivalents (GAE)) and total flavonoids content (TFC, expressed as mg quercetin/g of dry extract) for the crude extracts of C. spinosa and C. decidua were also evaluated. the antioxidant activity of the crude extracts obtained from both plants were assayed. Morevoer, the antioxidant activities of the crude extracts of both plants were evaluated using different methods including the DPPH radical scavenging activity, ABTS radical scavenging, ferrous ion chelating (FIC) and hydroxyl radical assay (HR) methods. The different screening results showed that the butanol extracts of both C. Spinosa and C. Decidua, contained the highest phenolics and flavonoids contents and exhibited the greatest antioxidant activities in all used assay methods. Results of the present study showed that antioxidant activities of C. Spinosa and C. Decidua have a direct relationship with their phenolic compounds and flavonoids content. The current study also revealed a good correlation between the total phenolic contents and the observed antioxidant activity of the crude extracts of C. spinosa and C. decidua. [ABSTRACT FROM AUTHOR]
