Mangroves are salt-tolerant forest ecosystem that extends between tropical and subtropical intertidal regions of the world.Mangroves are biochemically unique vegetation that produce wide array of natural products with immense medicinal potential.These plants are the most valuable resources and provide economic and ecological benefits to the coastal people.Natural products from these plants are of great interest as they provide innumerable direct and indirect benefits to human beings for the discovery of novel antimicrobial and other bioactive compounds.They possess active metabolites with some novel chemical structures that belong to diverse chemical classes such as alkaloids,phenol,steroids,terpenoids and tannins.Several mangrove species have been used in traditional medicine or have few applications as insecticide and pesticide.To date,several mangroves,and their associated species and solvent extracts are screened for antimicrobial activity along with the presence of potent bioactive compounds.The present article emphasizes and creates awareness about the potential mangrove plants and their associates as a source of biologically active compounds with potent antimicrobial properties.This paper also elaborates the mechanisms of action and various methods for screening of antimicrobial compounds.
