| 摘 要： | 通过测定还原力和自由基清除率确定了槐花提取物的抗氧化活性。结果表明:槐花提取物中黄酮类物质的含量为3.2596mg/ml。其还原力为强于VC而弱于TBHQ。槐花提取物清除羟自由基、超氧阴离子自由基和DPPH自由基时均存在良好的量效关系且呈线性关系,其中清除超氧阴离子自由基和DPPH自由基的能力较强,其IC50分别为66.55μg/ml和16.93μg/ml。

| 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. |
