Abstract
Moringa oleifera, a tree belonging to the Moringaceae family, is native to the southern
foothills of the Himalayas and is currently cultivated in virtually all tropical, subtropical, and
semi-arid regions of the world. It can grow under conditions of water scarcity, but its
intensive cultivation, with irrigation and fertilization, increases biomass yields to exceed 100
tons per hectare. The leaves, flowers, fruits and roots are appreciated for their nutritional
value and can be used in human and animal nutrition. The leaves are exceptionally rich in
vitamins and different amino acids. Reports on chemical composition reveal the presence
of different phytochemicals such as: glucosinolates, isothiocyanates, flavonoids,
anthocyanins, proanthocyanidins and cinnamates. The high content of vitamins, minerals
and other phytochemicals such as vanillin, omega fatty acids, carotenoids, ascorbates,
tocopherols, β-sitosterol, octacosanoic acid, moringin, moringinin and phytoestrogens is also
an important factor in the therapeutic effects of M. oleifera. Compounds isolated from
the plant such as benzyl isothiocyanate and benzyl 4- (α-Lramnopyranosiloxy) -glucosinolate
have anticancer, hypotensive and antibacterial activity. The scientific evaluation of the
processes of use of the plant, as well as the identification of active principles and mechanisms
of action, have made it possible to explain many of the previously known beneficial effects,
optimize their exploitation and propose new applications. The present work presents the
evaluation of the antimicrobial activity of moringa extract in order to provide a quantitative
scientific basis for its eventual use as an antimicrobial. To obtain the extract, different
methods were carried out, which were discussed about its performance and the qualitative
recognition of secondary metabolites
