无瓣海桑果实乙醇提取物及其不同极性萃取物抗氧化活性
Antioxidant activity of alcohol extract and different polar parts of Sonneratia apetala fruits
摘要
Abstract
The antioxidant activities of alcohol extract and different polar parts of Sonneratia apetala fruits were studied.The ethanol extract was obtained bv the addition of ethanol,and then successively extract by ethyl acetateand,butanol and the remaining liquid was collected to obtain n-butanol phase,ethyl acetate phase and aqueous phase residue.The antioxidant activity of all extracts were evaluated by superoxide anion radical,DPPH free radical,ABTS+ free radical scavenging ability and reducing ability.The results showed that all test samples had antioxidant activities and showed significant dose-effect relationship.Alcohol extraction showed medium antioxidant activity in the determination of DPPH radical scavenging and reducing ability.The ethyl acetate phase exhibited strong antioxidant activity in DPPH free radical,ABTS+ free radical scavenging and reducing ability,its DPPH free radical scavenging activity (IC50 =1.69 pg· mL-1) was obviously stronger than positive control vitamin E(IC50 =6.06 μg· mL-1),and its superoxide anion radical scavenging activity (IC50 =0.35 mg· mL-1)showed no difference from control(IC50 =0.30 mg·mL-1).关键词
