| Introduction: scientific studies have shown that Morinda citrifolia L. (noni) has antimicrobial activity against a large number of pathogenic bacteria and fungi. However, those studies report such activity in reference to the fruit, and there is little information about the leaves, roots and seeds of the plant. Objectives: evaluate the antimicrobial activity in vitro of various extracts from dry leaves and seeds of M. citrifolia L. (noni) and identify by thin layer chromatography the main secondary metabolites responsible for such antimicrobial activity. Methods: an evaluation was conducted of the antimicrobial activity in vitro of alcoholic, hexanic, chloroformic and ethyl acetate extracts from leaves and seeds of M. citrifolia L. (noni) against E. coli,... |
