The application of traditional Chinese medicine has a long history in China with unique advantages and functions. With the rapid development of separation and purification technologies, more and more polypeptide compounds with specific biological activity and medicinal value were isolated from natural plants. The plant polypeptides have a lot of biological activities, such as antitumor effect, antioxidize effect, antibacterial effect, hypoglycemic effect, blood pressure lowering effect, lipid-lowering effect, anti-fatigue effect, and so on. This review summarized the extraction method, purification method, biological activities, and prospects of plant polypeptides, providing a basis for further study of plant polypeptides.
