SCAVENGING OF SUPEROXIDE RADICAL ANION WITH HYDROXY CINNAMIC ACID DERIVATIVES: A PULSE RADIOLYSIS STUDY
【摘要】 采用脉冲辐解技术,利用竞争动力学方法测定了中性条件下3种羟基肉桂酸衍生物(咖啡酸、阿魏酸和芥子酸)与超氧阴离子自由基的反应速率常数,结合稳态分析,探讨了相应的反应机理。
【Abstract】 Using pulse radiolysis techniques the reaction rate constants of hydroxy cinnamic acid derivatives(HCAD) with superoxide radical anion(O 2 -· ) were obtained by competition reaction kinetic analysis. The reacting mechanism was proposed based on the HPLC analysis of final products and UV spectrophotometry.
