目的:探讨姜黄素(curcumin , Cur) 对超氧阴离子( O2 - ) 的消除效能。方法:采用 N B T/ P M S/ N A D H 体系产生 O2 - ,用比色法测定 Cur 对 O2 - 的清除能力。结果: Cur 能够清除 O2 - ,, S C50 约为82 .8 μmol/ L,相当于10 .3 U 的超氧化物歧化酶( S O D) 。结论: Cur 能够有效清除 O2 - 。
Objective: To investigate the elimination effect of curcumin (Cur) on superoxide anion (O2 -). Methods: O2 - was produced by N B T / P M S / N A D H system and the ability of Cur to scavenge O2 - was determined by colorimetry. Results: Cur cleared O2 -, and S C50 was about 82. 8 μmol / L, equivalent to 10. 3 U of superoxide dismutase (SOD). Conclusion: Cur can effectively remove O2 -.
