Polyphenol-Rich Date Palm Fruit Seed ( L.) Extract Inhibits Labile Iron, Enzyme, and Cancer Cell Activities, and DNA and Protein Damage.

Date palm fruit seed ( L.) extract (DSE), an under-utilized resource, is a rich source of polyphenols with high potency for disease prevention and antioxidative activities. For the first time, the present study demonstrated that DSE inhibits labile iron activity and DNA and BSA damage and inhibits acetylcholinesterase and tyrosinase activities.
