Abstract: Seaweed is an important marine life and an important source of food for people. Extensive previous studies have confirmed that seaweed contains a lot of protein. However, due to the low content of polypeptides, polypeptides are difficult to be extracted and purified by the traditional methods. At present, enzymatic hydrolysis and chemical extraction are more commonly used for extraction, and chromatography and membrane separation are used for purification. A higher purity polypeptides could be obtained from seaweed, and its structure was identified using MS-related technique. Seaweed polypeptides have a strong effect against tumor, and the mechanisms are manifested in many aspects. In this paper, the latest extraction, purification and identification methods of seaweed polypeptides, as well as the latest research progress of their anti-tumor activity were reviewed, so as to provide reference for their further development and utilization.

Key words: seaweed polypeptide, extraction, purification, antitumor activity
