| 摘 要： | 通过还原能力实验、1,1- 二苯基-2- 三硝基苯肼(DPPH)自由基清除实验、超氧阴离子自由基清除实验及过氧化氢清除实验研究亚麻木酚素的抗氧化性能。结果表明：亚麻木酚素开环异落叶松树脂酚二葡萄糖苷(SDG)具有良好的抗氧化活性；SDG的还原能力随质量浓度增加呈现出良好的线性关系；在质量浓度为150μg/mL 时，对DPPH自由基的清除率达到半数以上；对超氧阴离子自由基的清除率在质量浓度为0.3μg/mL 时达到55.81%；对过氧化氢清除能力随质量浓度的增加而升高，在150μg/mL 时达到最大值86.87% 后下降。

| Abstract: | To evaluate the antioxidant potential of secoisolariciresinol diglusoside (SDG), the abilities of SDG to scavenge DPPH and superoxide anion radicals and hydrogen peroxide, and its reducing power were assayed. Results showed that SDG had excellent antioxidant effect. Its reducing power was positively linearly correlated with concentration. SDG at 150 μg/mL could scavenge half of DPPH free radicals and more. A superoxide anion radical scavenging rate of 55.81% was observed for SDG 0.3μg/mL. The hydrogen peroxide scavenging capacity of SDG initially increased to a maximum of 86.87% at 150 μg/mL and then decreased as its concentration increased. |
