摘　　要：为拓宽葡萄园废弃物的资源综合利用途径,以酿酒葡萄品种‘白诗南(Chenin Blanc)’为试材,测定其废弃枝条与叶片中多酚物质含量及抗氧化性的季节性变化,以及葡萄植株不同部位含量的差异,并对‘白诗南’多酚类物质含量与抗氧化能力间的相关性进行分析。结果表明:‘白诗南’叶片中多酚类物质的含量多于枝条;不同营养器官对DPPH·清除力、羟自由基清除力(HRSC)以及铁氰化钾还原力(FRAP)存在差异,DPPH·清除力和FRAP的季节性变化趋势与总酚类似,不同器官中HRSC的动态变化则差异较大;‘白诗南’不同组织的抗氧化活性与其所含酚类物质含量呈显著或极显著正相关,其中FRAP与总黄酮之间的相关性最显著。In order to broaden the comprehensive utilization of vineyard waste resources,using Chenin Blanc as the test materials,experiments were conducted to study the seasonal changes of phenolic contents and antioxidant properties in abandoned branches and leaves of Chenin Blanc,as well as the difference of polyphenols content in different parts of grape were determined,and the correlation between polyphenols content and antioxidant capacity of Chenin Blanc were analyzed.The result showed that for the total phenolic contents,contents from leaves of Chenin Blanc surplussed that from canes.DPPH·radical scavenging capacity,hydroxyl radical scavenging activity and potassium ferricyanide reducing power of different grapevine organs changed differently.DPPH·radical scavenging capacity and potassium ferricyanide reducing power varied similarly with the total polyphenols,while hydroxyl radical scavenging activity in different organs changed greatly.Correlation analysis showed that polyphenols remarked positive or significant positive correlation to the antioxidant capacities of grapevine organs,and potassium ferricyanide reducing power boasted the most significant correlation to the total flavone.
