Antioxidant Activities of Ethanol Extracts of Different Buckwheat

Tian Cheng-rui

Abstract

The total phenolics, reducing power, metal chelating activity, DPPH radical scavenging activity, along with hydroxyl radical scavenging activity of the ethanol extracts of five buckwheat groats were studied. The results demonstrated that all tested buckwheat extracts showed very good antioxidant activity with dose-effect dependent, and the positive correlation among the content of total phenolics, reducing activity and antioxidant activity were also observed.
