摘要

目的: 研究金铁锁体外抗氧化活性。方法: 采用清除采用清除二苯代苦味酰基(DPPH)自由基、清除 (ABTS)自由基及铁离子还原/抗氧化能力(FRAP)测定法

对金铁锁体外抗氧化活性进行评价

并阳性对照没食子酸丙酯(PG)、丁基羟基茴香醚(BHA)和二丁基羟基甲苯(BHT)比较。结果: 金铁锁3个提取物体外抗氧化活性均弱于阳性对照PG

BHA

BHA。在3个提取物中

金铁锁乙酸乙酯提取物清除ABTS自由基(IC50=40.54 mg·L-1)及还原Fe3+的能力·g-1]较强;正丁醇清除ABTS自由基(IC50=83.38 mg·L-1)及还原Fe3+的能力·g-1]次之

石油醚提取物最弱。结论: 金铁锁乙酸乙酯部位体外抗氧化活性较强。

Abstract

Objective: To study the antioxidant activity Psammosilene tunicoides in vitro. Method: Antioxidant activities of P. tunicoides were evaluated by the 1

1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging

diamonium salt (ABTS) radical scavenging and ferric reducing antioxidant power (FRAP) assay. Results were compared with that of positive controls PG

BHA and BHT. Result: Antioxidant activity of three extracts from P. tunicoides was weaker than that of the positive control PG

BHA and BHA. In the three extracts

Antioxidant activities of ethyl acetate extract was good. ABTS radical scavenging (IC50=40.54 mg·L-1) and ferric reducing antioxidant power 2.42) μmol·g-1] of ethyl acetate extract were strong

followed by the ABTS radical scavenging (IC50=83.38 mg·L-1) and ferric reducing antioxidant power·g-1] of n-butanol extract

petroleum ether extract was the weakest. Conclusion: Ethyl acetate extract of P. tunicoides had strong antioxidant activity.
