The effect of plant extracts of Moringa Oleifera on Some Pathogens Isolated from the oral cavity of Diabetic mellitus type 2 Patients

The current study aims to examine or evaluate the biological activity of the plant extracts of Moringa oleifera in the Samawa governorate and the aerial parts of plants was extracted by a Soxhlet extractor, using two types of solvents are characterized by different polarity: methanol and hexane, and determine the active compounds by using Gas Chromatography Mass Spectrometry (GC-MS).The GC results for the Moringa extract with methanol showed 9 active compounds, while the Moringa extract with hexane showed 24 active compounds. The antimicrobial activities of the crude extracts are tested against three species of pathogenic bacteria and fungi consisting of two gram positive bacteria: Streptococcus mutants Enterococcus feacalis and one fungus is Candida albicans, based on disc-diffusion assay and determine the Minimum extract four concentrations of each Inhibitory Concentration (MIC). Formed: (0, 25, 50, 75 mg/ml). Were the results of the inhibitory activity of the extracts varied according to the type of extract itself and the different bacteria tested? Generally, Moringa oleifera extracts show strong inhibition against all bacteria, and fungi, especially hexane extract and methanol
