抗氧化剂阿魏酸自组装金纳米颗粒的体外抗氧化
In Vitro Antioxidant Activity Study of Ferulic Acid Self-Assembled Gold Nanoparticles
摘要
Abstract
The antioxidant protection effects of ferulic acid nanoantioxidant on macrophage cells were studied and the free radical-inhibiting activities of ferulic acid nanoantioxidant were determined at the cellular level using electron spin reso-nance-spin trapping and UV-spectrum method.The results illustrates that the nanoantioxidant could eliminate the reactive oxygen species stimulated by t-BuOOH in cells more effectively than that of antioxidants monomers.Meanwhile,the lipid peroxide detection of malondialdehyde by spectrum method also proved that the nanoantioxidant have a high antioxidant activity on t-BuOOH stimulated macrophage cells.Therefore,it could be concluded that the self-assembled nanoantioxi-dant have a potential for the enhancement of antioxidant activity.关键词
