| 摘 要： | 以山东大瓜枣为试材，研究1-甲基环丙烯（1-MCP）负压渗透处理对鲜枣贮藏期间生理指标及抗氧化能力的影响。结果表明：1-MCP处理可以维持鲜枣果实体内较低的活性氧水平（H2O2），提高果实自身抗氧化能力（T-AOC、OH·、O2·-、DPPH），维持果实自身的抗氧化物质抗坏血酸（AsA）及总酚含量；1-MCP处理对果实过氧化氢酶（CAT）呈现抑制表达作用，而对于抗坏血酸过氧化物酶（APX）、超氧化物歧化酶（SOD）、多酚氧化酶（PPO）和过氧化物酶（POD）则有一定的激活作用。

| Abstract: | The changes of antioxidant activities in Shandong Dagua Jujube (Ziziphus jujube Mill cv. Dagua) fruits treated with 1-MCP negative pressure osmosis were studied. The contents of H2O2 , total phenols and ascorbic acid, activities of OH·, O2·- and DPPH· scavenging rates, catalase(CAT), peroxidase(POD), polyphenoloxidase(PPO) activities were investigated. The results showed that 1-MCP treatment decreased the level of active oxygen (H2O2) and increased the antioxidation activities of the fresh fruits(T1-MAOC，OH·，O2·-，DPPH·). During the storage, the contents of total phenols and ascorbic acid in 1-MCP treated fruits were higher than untreated control. Meanwhile，the activity of CAT was restrained in 1-MCP treatment group and the activities of other enzymes(APX,SOD,PPO, and POD) were activated by 1\|MCP at a certain degree. |
