Study on Antioxidant Activities of Pogadatree Flower (Robinia Pseudocacia L.) Extracts

Abstract

Abstract: The antioxidant activities of pogadatree flower(Robinia Pseudocacia L.)extracts(PFE)were researched through determinations of reducing power and scavenging free radicals active of PFE.The results showed that:content of flavonoid in PFE was 3.2596 mg/ml.The reducing power of PFE was higher than VC and lower than TBHQ.There were well relationships between the contents of PFE and activities of scavenging hydroxyl free radical,superoxide anion free radical and DPPH radical and appeared linear relationships.Of them,the abilities of scavenging superoxide anion free radical and DPPH radical are stronger,the IC50 are 66.55μg/ml and 16.93μg/ml,respectively.

Key words: pogadatree flower (Robinia Pseudocacia L.), flavonoid, antioxidant activity
