Abstract:[ Objective ] The aim was to study the antioxidant activity of 10quat peel pigment extract in vitro. [ Method ] The antioxidant activity of loquat peel pigment extract in vitro was evaluated by total reducing power, scavenging capacity against DPP · and ABTS · , and metal chelating ability. [ Result] The loquat peel pigment extract exhibited some antioxidant activity in a concentration-dependent fashion. It had scavenging capacity against DPPH ~ , ABTS ~ , and metal chelating ability with 1C5o values of 253.69, 81.23,273.42 μl. [ Conclusion ] The loquat peel pigment extract exhibited some antioxidant activity in vitro. So, it could be taken as a kind of natural pigment with antioxidant ac- tivity for further development and utilization.
Keywords:Loquat peel  Pigment  Antioxidant activity
