摘要: 采用清除二苯代苦味酰基 ( DPPH) 自由基、清除[2,2-连氨-(3-乙基苯并噻唑啉-6-磺酸) 二氨盐] ( ABTS) 自由基和铁离子还原/ 抗氧化能力 (FRAP) 测定法对疏毛绣线菊总抗氧化活性行评价,将测定结果与阳性对照药物二丁基羟基甲苯 (BHT) 进行比较。研究结果发现疏毛绣线菊正丁醇部位具有较强的清除DPPH自由基 (IC50=42.2 μg/mL) 和还原Fe3+的能力 (TEAC =1052.46 μmol/g),乙酸乙酯部位清除ABTS自由基能力 (IC50=6.4 μg/mL) 较好,但均弱于阳性对照药物BHT (IC50和TEAC值分别为23 μg/mL、2.3 μg/mL和1532.7 μmol/g)。实验证明疏毛绣线菊正丁醇部位体外抗氧化活性较强。

Abstract: 1,1-diphenyl-2-picryl-2-picrylhydrazyl (DPPH) radical scavenging,[2,2′-azino-bis-3-ethylbenzo-thiazoline-6-sulfonic acid]diammonium salt (ABTS) radical scavenging and ferric reducing antioxidant power (FRAP) assay were used to evaluated the extracts of Spiraea hirsuta (Hemsl.) Schneid with BHT as positive control.The results showed that the n-butanol extract of S.hirsuta showed higher scavenging activity against DPPH radical (IC50=42.2 μg/mL) and ferric reducing antioxidant power (TEAC=1052.46 μmol/g).The ethyl acetate extract had better ABTS radical scavenging activity (IC50=6.4 μg/mL),but weaker than that of BHT (IC50 and TEAC were 23,2.3 μg/mL and 1532.7 μmol/g,respectively).The n-butanol extract showed the highest antioxidant activity in vitro.
