Abstract:A large amount of waste fruit residues has been outputting in the production process of olive oil，which was often piled up or burned in large quantities and cannot be used rationally so as to cause serious environmental pollution.As the main natural active ingredients in pomaces of Olea europaea，polyphenols have many biological activities，such as anti-oxidation，anti-hypertension，anti-atherosclerosis，anti-inflammation and hypoglycemic.In order to better exploit and utilize the polyphenols from olive fruit residues，the extraction technology and biological activity of polyphenols were summarized，and the prospect of its development was forecasted.
