Abstract

Four plants (Aerva javanica, Euphorbia retusa, Haloxylon salicornicum, and Launaea nudicaulis) that are commonly growing in Egypt were screened for their phytochemical content and antioxidant potential. Each plant had its own methanolic extract made and tested. Quantitative analysis were utilized to estimate alkaloids, tannins, saponins, flavonoids, and phenols, while qualitative phytochemical assays were employed to determine the existence of bioactive substances. The antioxidant capacity of these extracts was measured using DPPH (diphenyl -1, 2-picryl hydrazyl). In the present results, the following is the order of phytocomponents found in the plant species that have been studied: E. retusa > L. nudicaulis > H. salicornicum > A. javanica. Regarding to antioxidant potency, IC50 values for the four plant samples range from 57.68 mg/ml for Launaea nudicaulis to 62.27 mg/ml for Euphorbia retusa to 71.35 mg/ml for Haloxylon salicornicum to 90.98 mg/ml for Aerva javanica. All the extracts examined had antioxidant scavenging activities, however at concentrations greater than catechol (IC50 = 15.23 mg/ml). Antioxidant-active phytochemicals found in these plants may give a solid rationale for their traditional medical usage.
