摘　　要：总结了抗氧剂的作用机理、发展趋势和结构与抗氧性的关系。抗氧剂作用机理包括链终止剂、过氧化物分解剂和金属离子钝化剂,其中链终止剂包括氢给予体、自由基捕捉剂和电子给予体;抗氧剂的发展趋势包括多功能化、反应型和天然抗氧化。The antioxidation mechanisms, development trend, and relationships between structure and ant/oxidation property of several main kinds of antioxidants were reviewed. The antioxidation mechanisms included chain termination, peroxide decomposition and metal ion deactivation. The chain terminator included hydrogen donor, free radical scavengers, and electron donor. The work on multi functional, reactive, and natural antioxidants constituted the developing trend.
