| dc.description.abstract | :This study involves phytochemical screening, Antibacterial Activity, antioxidant, total phenolic content, for the medicinal indigenous plants from Libya (, Lycium shawi ,Cymbopogan Citratus i). Leaves extracts of the selected medicinal plants Phytochemical screening: The results of phytochemical screening of methanolic and chloroform extracts obviously show that presence of each tannin, phenols, flavonoids, alkaloids, saponins, cardiac glycosides and carbohydrates, Antibacterial Activity: Through Disk Diffusion Method, extracts were examined against the activity of Gram-negative pathogenic bacteria Escherichia coli, where, the methanolic extracts revealed a good inhibition effect result, Whereas chloroform extracts revealed a vulnerable inhibition effect result against Escherichia coli,Antioxidant Activity: Antioxidant potential of the extracts was analyzed as contents of total phenols and free radical scavenging activity extract were assessed by the declaration of a methanolic solution of 2, 2- diphenyl-1-picrylhydrazyl DPPH. Results of antioxidant activities were determined in three concentrations: 50mg/ml, 100 and 200 mg/ml of each extract. And showed that at increasing the concentration, the susceptibility extracts tending to increase also for DPPH. | en_US |
