Abstract
Oxidative stress and reactive oxygen species have been linked with the commencement of a variety of chronic human diseases such as atherosclerosis, diabetes mellitus, chronic inflammation, neurodegenerative disorders and certain types of cancer. The exigency of components with antioxidant efficacy is growing as it is recognized. The antioxidant effects of these components are mainly assigned to scavenging efficacy against hydroxyl and superoxide radicals, quenching singlet, triplet oxygen, chelating ability, and reducing power. There are various artificial antioxidants such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), Propylgallate (PG) and butylated hydroxyquinone (TBHQ) are commercially obtainable and actually applied. However, the use of these artificial antioxidants for medicine or food components has been bounded by the toxicity and safety that can develop to the problems of the potential health in human. Therefore, many investigators have owing interest to many types of innate antioxidants that can be used without toxicity in human. Marine algae are known to be a wealthy source of these components. Antioxidant efficiency has been announced in a great kind of marine algae, including green, brown and red algae. Natural antioxidants from algae are known to play a significant function against various diseases. The discovered antioxidant components in algae from taxa related to these groups have effort anti-inflammatory, anti-aging, dietary, antimicrobial, cytotoxic, antimalarial, anti-proliferative, and anticancer properties. Therefore, the present overview was summarized in the recent research on the antioxidant efficacy of marine algae, methods, and components.
