摘　　要：采用羟自由基(·OH)体系检测并研究比较新疆不同产地葡萄树伤流液的体外抗氧化活性。结果表明:新疆葡萄树伤流液具有较强抗氧化活性,特别是对·OH的清除能力较强。不同产地葡萄树伤流液中,和田红葡萄树伤流液对·OH清除率最大为83.35%,是0.01mg/mLVc的2.5倍。阿图什和喀什红葡萄树伤流液·OH清除率分别为57.15%、50.58%,而吐鲁番无核白葡萄树伤流液对·OH清除率与Vc相近;研究还发现,和田红葡萄树伤流液对.OH清除率具有较强的热稳定性。The antioxidant activity in grape tree bleeding was studied by detecting hydroxyl free radicals（ · OH）. The scavenging activity on · OH. The ratio of scavenging on Kashi, Tulufan were 83.35%, 73.36%, 57.15%, 50.58% times than vitamin C （0.01 mg/mL） while Tulufan was aim tree bleeding sap showed highly thermal stability. sap from different regions in Xinjiang province result showed that the bleeding sap have strong · OH of those samples from Hetian, Atushi, and 32.45% respectively, the highest was 2.5 ost the same as Vc. Besides, Hetian red grape
