Abstract: This paper presents breeds, classifications and applied investigations of the natural pigments added to foods, drugs and cosmetics. And it includes physicochemical properties of, health care and medical treatment effects of and isolation and purification methods (such as solvent extraction, microwave and ultrasonic wave assisted extraction and supercritical carbon dioxide fluid extraction and high pressure extraction) of the natural pigments. Also, it reviews the social significance and the economic value of the natural pigments in comparison with the synthetic coloring agents which have toxicity and by-side effects. 

Key words: natural pigments; synthetic coloring agents; physicochemical properties; classifications; extraction; application
