“…The extracts have sometimes been indicated to contain a variety of families of chemical compounds (Fuglie, 2001;Ani et al, 2018). The extracts of the plant M. oleifera have sometimes been indicated to contain a variety of families of chemical compounds including essential amino acids, tannins, alkaloïds, phenols, β-carotenes, flavonoids, calcium, potassium, phosphorus, vitamin A, C and D among others (Kuete, 2010(Kuete, , 2017Arora et al, 2013;Metsopkeng et al, 2019Metsopkeng et al, , 2020. Their impact on the growth of bacteria on the blood has also been indicated (Latifa and Muneera, 2016).…”

“…In several regions of the world, these extracts are also used in traditional medicine to fight against fever, tuberculosis, anemia, skin infections and respiratory disorders (Fuglie, 2001). They are sometimes used to fight against some microorganisms of health importance including Escherichia, Salmonella, Pseudomonas, Staphylococcus, Aeromonas, Bacillus, Aspergillus, Penicillium, Rhizopus and Candida cells species (Elgamily et al, 2016;Metsopkeng et al, 2019Metsopkeng et al, , 2020. Most of the above microorganisms are waterborne and the strains of some species are commensal, whereas other can be opportunistic pathogens and can thus cause harm to immunocompromised individuals (Kurosu et al, 2013;Mechergui et al, 2019).…”

This study aimed at assessing the MICs (Minimum Inhibitory Concentrations) and the MBCs (Minimum Bactericidal Concentrations) of the methanolic extracts from 4 different parts (leaves, seeds, stem, roots) of the plant Moringa oleifera against the bacteria E. coli and S. aureus. Phytochemical profile of each extract has been determined using LC/MS analyses. Microbial analyses were done using 96-wells plate method. Results showed that the four parts on the plants contain heterosides and glucosinolates. Iridoids were found in leaves, stem and roots. Flavonoids were found in leaves and stem. Phenolic acids were found only in leaves and carboxylic acids found only in stem. The abundance and the number of identified compounds of a given class varied from one part of plant to another. The MICs and MBCs varied with respect to the microorganism and the part of the plant. With E. coli, the MICs varied from 0.009 (leaves) to 1.25 mg/mL (seeds), and the MBCs varied from 0.156 (leaves) to 2.5 mg/mL (seeds and stem). With S. aureus, the MICs varied from 0.009 (stem and roots) to 0.039 mg/mL (leaves and roots), and the MBCs varied from 0.078 (leaves) to 4 mg/mL (stem). The bactericidal or bacteriostatic properties of the extracts varied depending on the part of the plant and the microorganism considered. Against E. coli, the leaves, stem and roots extracts were bacteriostatic whereas seeds extract was bactericidal. Against S. aureus, the seeds, stem and roots extracts were bacteriostatic whereas leaves extract was bactericidal.

Objective: This study was conducted to investigate the phytochemical constituent of Moringa oleifera leaf extract and determine the inhibition of these extract against Escherichia coli bacteria. Methodology: This was a laboratory experimental study. Moringa leaves was collected from Semau Island, East Nusa tenggara, Indonesia. Quantitative testing was carried out to determine the bioactive components of Moringa leaf extract. The well diffusion method was used to test the inhibitory activity of moringa leaf extract against E. coli. The treatment were divided into 10 extract concentrations (10%, 20%, 30%, 40%, 50%, 60%,70%, 80%, 90%, 100%). Results: This study showed the presence of flavonoids, phenols, alkaloids, tannins and saponins in M. oleifera leaf extract. M. oleifera leaf extract has different inhibitory properties against E. coli bacteria. Moringa extract concentrations of 10%, 20% and did not show inhibitory activity against E. coli while the others concentrations were able to inhibit the growth of E. coli. The average inhibition zone diameter for each concentration varied i.e 1.91 mm (40%), 6.27 mm (50%), 8.53mm (60%), 10.39 mm (70%), 12.80 mm (80%), 14.84 mm (90%) and 19.04 mm (100%). The most effective for inhibiting the growth of E. coli bacteria was 100%. The results of statistical analysis using repeated ANOVA tests obtained p value 0.001 (p<0.05) that means the M. oleifera leaf extract able to inhibit E. coli. Contributions: We conclude that M. oleifera leaves have the potential as an antibacterial, so further studies related to the use of M. oleifera in overcoming various environmental health problems is needed.
