Abstract:
This is a retrospective analytical study, conducted at the Department of
Microbiology, Sudan University of Science and Technology. The study was carried
out in the period from April to August, 2012.
The objective of this study was to screen antibacterial activity of Moringa oleifera
leaves and seeds extract against standard bacteria and clinical bacterial isolates.
The extraction of Moringa leaves and seeds were carried out with methanol 80 %
using soxhlet extractor apparatus.
Extract was then filtered through filter paper and evaporated under reduced
pressure using rotary evaporator apparatus.
The antibacterial activity was determined by the agar well diffusion method, the
antibacterial activity was evaluated by measuring the diameter of the zone of
inhibition observed.
The study of the Moringa oleifera leaves and seeds extract showed prominent in
vitro antibacterial activity against all used bacterial species, and the antibacterial
activity of leaves extract is stronger than antibacterial activity of seeds extract.
These results had shown the possibility of using this tree in the treatment of
diseases caused by these pathogens. Further studies are required to screen other
.parts of this tree as well as to investigate its toxicity
