Abstract

The search for knowledge of biological activities and phytochemical screening of the species Morus alba L. is non- existent, however the present study came to explore this plant. To perform the phytochemical screening and the evaluation of the antimicrobial activity of the leaves of the species Morus alba L. Experimental analysis, with the collection of leaves of the species to obtain hydroalcoholic extract at 70% and from this extract the main secondary metabolites were identified. And after contributing to the systematic knowledge of the secondary metabolites of Morus alba L., antimicrobial activity was tested from the concentrated extracts of the leaves of the species. Among the extracts tested, the one that presented the most inhibitory activity in S. aureus was the concentrate, then the aqueous and finally the alcoholic. In E. coli strains the extracts showed no effects. Phytochemical tests were performed using the concentrated extract using the methods of reference [1], where it presented the presence of reducing sugars, phenols and tannins, alkaloids and depsides and depsidones. The research emphasized the microbiological action of the species Morus alba L., as it is a poorly studied plant and may help in the future in the development of new drugs. Phytochemical studies were necessary to confirm this microbiological action, as they were essential for the identification of natural and efficient antibacterial agents.
