Olive polyphenols are a series of phenolic antioxidants extracted from the fruit and leaves of olive. The main active components of olive polyphenols include gallic acid, coumaric acid, tyrosol, hydroxytyrosol and oleuropein, which have many pharmacological actions, such as antioxidation, antiinflammation and antibacterial, hypoglycemic and lipid-lowering, and prevention and treatment of cardiovascular diseases, and have good prospects in the fields of medicine, health care products and cosmetics. The major sources, chemical compositions, pharmacological action and main extraction technology of olive polyphenols were reviewed, and the future research and development of olive polyphenols were prospected so as to provide reference for the comprehensive development and utilization of olive resources and olive polyphenols. |
