Abstract: Seaweeds are a rich source of bioactive compounds as discovered by many research studies in recent history. Even though there are numerous methods to generate certain bioactive compounds from chemical modifications, advantages of extracting them from natural seaweeds have exceeded the artificial synthesis. However, practical applications of seaweeds are mainly observed to pharmaceutical industry, drug development and functional foods so far. This is due to the bioactive properties such as antiviral, antitumor, anticancer, anti-inflammatory and antilipidemic beneficial for such industries.
