Abstract: The growing rate of the activities of microbes increases every day. Virtually everything that surrounds man are contaminated and polluted with these microbes. These contaminations have led to some infectious and contagious diseases some of which are curable and others deadly. The advancement in Science and Technology have helped reduced this problems to certain level. In doing this, different researches have been carried out on medicinal plants in order to combat these problems. In this research, phenolic compounds were found broadly distributed in the plant kingdom and are the most abundant secondary metabolites of plants. They are reactive metabolites in a wide range of plant-derived foods and mainly divided in four groups: phenolic acids, flavonoids, stilbenes and tannins. They work as terminators of free radicals and chelators of metal ions that are capable of catalyzing lipid oxidation. Therefore, this review examines the functional properties of phenolics and their health benefits.
The introduction of natural antimicrobial and antioxidant agents that are environmental friendly and non-pollutant or contaminate the environment are inevitable.
