Phytochemical screening and antimicrobial investigation of Moringa oleifera leaf extracts (original) (raw)

Phytochemical And Antimicrobial Studies On Moringa Oleifera Leaves Extracts

IOSR Journal of Environmental Science, Toxicology and Food Technology, 2014

The antimicrobial and medicinal properties of Moringa leaf extracts was examined through Phytochemical screening on the solvent extract and conducting bioassay on the target microorganisms: E. coli and Salmonella. The phytochemical screening of the plants constituents were assessed by using qualitative methods. Tests were conducted for the presence of the following active components: alkaloid, tannins, phlobatannins, phenol, flavonoids, glycoside, saponins, volatile oil, hydrolysable tannin and protein. All were present. The ethanol extract of the leaf was active against E. coli and salmonella measuring clear zones of inhibition 3.0mm and 14.0mm respectively. This indicate the presence of these bioactive components in Moringa, which proves its potency in the treatment of some bacterial infections

Phytochemical screening of Moringa oleifera leaf extracts and their antimicrobial activities

Cellular and Molecular Biology, 2020

Moringa oleifera is a tree native to tropical and subtropical regions of South India and used in traditional medicine. The aim of this study was characterize the phytochemicals present in M. oleifera leaf extracts and study their antimicrobial activities. Solvent extractions with Soxhlet apparatus of leaves were obtained using hexane, benzene, isopropanol, methanol, and water. The crude extracts were concentrated and screened for qualitative phytochemical analysis, and the antibacterial, antifungal and antiviral activities of crude extracts were measured by in vitro methods. Alkaloids, carbohydrates, tannins, phenolic compounds, terpenoids, cardiac glycosides, amino acids, oils and fats were found in the different crude extracts analyzed. Water and methanol extracts showed antibacterial activity against all selected bacteria, hexane and benzene extracts showed antifungal activity against all fungi tested, and hexane, benzene and isopropanol extracts showed activity against Hepatitis...
