The antioxidant capacity of peanut shell polyphenols interacted with pancreatic α-amylase is examined in vitro. The results indicated that peanut shells polyphenols could be used as a kind of potential natural antioxidant for food. The polyphenols easier binding to proteins made its scavenging activities decreased in complex biological mixtures when binding to the α-amylase which include phlorglucinol, luteolin, pyrogallol, and catechin. From the results, the decreasing extention had a tight relationship with the structure of polyphenol. A carbony group at C (4) in the polyphenolic molecule showed great effect on interaction between polyphenols and α-amylase which leading a higher decrease in scavenging activities of peanut shells polyphenols. And meta-position polyphenolic hydroxyls were more active than adjacent polyphenolic hydroxyls in the interaction with α-amylase.
