Seaweeds- A Source of Potential Bioactive Compounds

Seaweeds as a potential source of diet have been used in Japan, Korea and China since prehistoric times. In fact the usage of kelps dates back to 5th century in China. Seaweeds are having unique bioactive compounds and its composition, and nutritional benefits, its structures have been widely studied and are currently being therapeutically used for many medical conditions. Their sustainability in harsh environmental conditions is another unique characteristic that is of researcher’s interest. In the current review, we have gathered important information on various bioactive compounds such as Complex Polysaccharides, Unsaturated Fatty Acids, Dietary Fibres, Polyphenolic compounds from seaweed, Phloroglucinol derivatives, Porphyrin derivatives, Proteins and Mineral constitutions, and other Seaweed Phytochemicals. Although are part of daily food in coastal regions of west, not much research is focused in Indian coastal areas to extract these bioactive components or to utilize these algal blooms. We need to utilize our regional algal blooms and proper techniques must be developed and streamlined for using our natural bioresource
