实施例9 DPPH自由基清除实验
DPPH是一种比较稳定的脂性自由基,其N上有一个游离电子,其甲苯溶液呈紫色,在517nm处有最大的吸收峰。加入抗氧化剂以后,DPPH捕捉一个电子与游离电子配对,紫色褪去,变为无色物质,在517nm处的吸收消失,其褪色程度与其接受的电子数成定量关系。依此原理用分光光度计检测DPPH自由基与试样液反应后吸光值的变化,可检定试样提供氢原子、清除自由基抗氧化的能力。实验表明,该法简便易行,灵敏可靠。
实验方法:
(a)DPPH测试液的配制:精确称取一定量的1,1-二苯基-2-苦基肼自由基,用甲苯溶解为2×10-4 mol/L的DPPH溶液,避光冷藏放置。
(b)待测液的配制:Vc(阳性对照)、羟基酪醇己二氨基甲酸酯(样品)和羟基酪醇(对照品)。用甲苯将样品液进行梯度稀释,同时采用一定量的甲苯将2组对照分别溶解于试管中,制成与样品相同的浓度梯度。得到相应的2组对照溶液(梯度设置见表1)。
(c)操作方法:
样品液吸光度测定:取样品液 (表1A) 2mL,加入浓度为2×10-4 mol/L的DPPH溶液2mL,混匀后在室温下避光反应30min,以甲苯调零,在517nm处测定其吸光度Ai,同时测定2mL甲苯与2mL样品溶液混合后的吸光度Aj以及2mL DPPH溶液与2mL甲苯混合后的吸光度Ao(实验结果见表2)。
对照品吸光度测定:取(b)步骤对照品溶液(表1 Vc、B)2mL,加入浓度为2×10- 4mol/L的DPPH溶液2mL,混匀后在室温下避光反应30min,以甲苯调零,在517nm处测定其吸光度Ai,同时测定2mL甲苯与2mL对照品溶液混合后的吸光度Aj以及2mL DPPH溶液与2mL甲苯混合后的吸光度Ao(实验结果见表2)。
(d)清除率的计算:清除率(%)=[1-(Ai-Aj)/Ao]×100%
根据表1~3与图1实验结果可知,羟基酪醇己二氨基甲酸酯(A)以浓度依赖性方式表现出对DPPH明显的清除作用。其对DPPH的清除率从19.87%(1.76 ppm)到97.14%(915.20ppm),与单一的羟基酪醇(B)相比,同等浓度下羟基酪醇己二氨基甲酸酯(A)清除DPPH自由基的能力明显更好。同时,与阳性对照Vc相比,羟基酪醇己二氨基甲酸酯(A)的清除能力接近。以上实验结果证明该化合物具有优良的抗氧化活性,可以作为一种新型的抗氧化添加剂应用于食品、医药、保健品、化妆品领域。
