ABSTRACT

Bio-products derived from marine origins have a medicinal potential library. Marine bio- organisms rich in secondary metabolites ranging from cyclic peptides to aromatic alkaloids entice researchers to seek new therapeutic value and discover novel drugs for the treatment of chronic medical conditions such as skin, CNS, gastric, lymphatic, reproductive disorders, cancer, and AIDS. This review on marine bio-products- comprises of a condensed data set relating to antioxidant activity on marine- derived products. These chemicals shield cells from the damaging effects of unstable molecules known as free radicals. The marine environment offers a diverse range of habitats from which to derive novel sources of natural products. Marine organisms generate a
wide range of metabolites with novel chemical structures and powerful biological activities. Antioxidants are synthetic or natural substances that can prevent or postpone certain types of cell damage. These molecules shield cells from the damaging effects of unstable molecules known as free radicals. Marine bacteria have not been studied as thoroughly as terrestrial bacteria for antioxidant compounds. The bioactive metabolites extracted from seaweed and sponges, as well as their associated bacteria, were found to have good antioxidant activity, which requires further investigation in terms of drug discovery.

Keywords: Macroalge; bioactive metabolites; Antioxidant activity; reactive oxygen species.
