Content and Antioxidant Activity of Polypenols from 8 Fagaceae Plants
Objective:To screen the polypenols with high content and strong antioxidant capacity,and to encourage the development of Fagaceae resources.Method:The total content of polypenols from 8 kinds of Fagaceae plants were determined by Folin-phenol method,and their antioxidant capacities were evaluated by four antioxidant methods,including 1,1-diphenyl-2-pieryl-2-picrylhydrazyl (DPPH) scavenging,2,2-amino-di (3-ethyl-benzothiazoline sulphonic acid-6) ammonium salt (ABTS) radical scavenging,Fe2+ chelating,and Fe3+ reducing assays.The relationship between the total polypenols content and antioxidant capacity was analyzed.Result:The Castanopsis hystrix had the highest total polypenols content (10.61％),and followed by C.fissa (10.09％).Comprehensive evaluation of antioxidant capacity test results showed that all plants had good antioxidant capacity,and the C.hystrix had the strongest antioxidant capacity.A dose-effect relationship between the antioxidant capacity and the total polypenols content of C.hystrix was found.Conclusion:C.hystrix and C.fissa were the most potential plant resources for the health and skin care products with antioxidant activity.
