Antimicrobial activity, DPPH assay- Lycopene, Phenolic compounds, Radical scavenger activity


The widespread use of medicinal plants for health purposes has increased dramatically due to their great importance to public health. In this study, the levels of phenolic, flavonoid, β-carotene and lycopene compounds of Anastatica hierochuntica and Hyphaene thebaica were determined. The plant extracts were evaluated for their antioxidant activities using various antioxidant methodologies: (i) scavenging of free radicals using 2, 2-diphenyl-1-picrylhydrazyl, (ii) metal ion chelating capacity, and (iii) scavenging of superoxide anion radical. The antimicrobial activity of both plant extracts was evaluated against a panel of microorganisms using the agar disc diffusion method. The total phenolic content (51.97 and 64.9 mg/g dry weight in A. hierochuntica and H. thebaica, respectively) was significantly (p < 0.05) different. The antioxidant activity increased with an increase in concentration. The plant extracts were more active against Gram-positive bacteria than Gram-negative bacteria. Also, the antimicrobial activity of H. thebaica was higher than that of A. hierochuntica methanolic extracts. This study reveals that the consumption of these plants would exert several beneficial effects by virtue of their antioxidant and antimicrobial activities.
