Abstract: The antioxidant activities in vitre of the petroleum ether,EtOAc,BuOH and H2O extracts of the folk edible flowers of Juglans regia L. were studied by the DPPH radical scavenging activity method,respectively. It was found that the edible flowers of Juglans regia L. exhibit good scavenging activity on DPPH radical. The IC50 value of the EtOAc extract is 30.7μg,which shows a higher activity than BHA.
