沙棘果粉体外抗氧化活性的研究马宁安耿春峰何茂军鲁平原(青海圣烽生物技术开发有限公司,青海西宁 810016)摘要 :采用不同方法测定沙棘果粉的抗氧化能力活性
实验条件下,沙棘果粉对DPPH 自由基、超氧阴离子O2-、羟基自由基(·OH)、过氧化氢H 2O2 有较强的清除或抑制作用,且显示较好的量效关系
所以沙棘果粉有效成分具有较好的抗氧化作用

, LTD, Xining ,810016)Adopting different determination methods, the activity of antioxidant capacity of sea buckthorn fruit powder was studied
Under experimental conditions, sea-buckthorn fruit powder has antioxidant capacity to DPPH, superoxide anion free radical O2-, hydroxyl radicals (
OH), hydrogen peroxide H2O2, and shows good concentration relationship with activity of antioxidant capacity
Results show that sea-buckthorn fruit powder has good anti-oxidation active
