Abstract: Extraction of natural antioxidant in Flos Sophorae Immaturus was discussed. Three methods investigatedthe natural antioxidant resistance in Flos Sophorae Immaturus to free radical by means of ESR, scavenging of DPPHand photometric system. Scavenging percentage of free radical of Rutin in Flos Sophorae Immaturus would reach40%~70%,so it could be used as a kind of new food additive for antiradicals.

Key words: Flos Sophorae Immaturus, Rutin, analysis of free radical, antioxidant, food additive, DPPH
