摘要: 采用流动注射化学发光法研究了绿茶、红茶和乌龙茶的抗氧化性能。实验结果表明:绿茶、红茶和乌龙茶能有效的抑制超氧阴离子自由基诱导的鲁米诺化学发光,并且随着发光体系中绿茶、红茶和乌龙茶浓度的升高,发光强度呈现下降趋势即具有较强的抗氧化性能,对绿茶、红茶和乌龙茶的抗氧化性能进行了比较。

Abstract: The antioxidation effects of green tea, black tea and wulong tea were studied by the flow-injection chemiluminescence.The results indicated that natural tea, black tea and wulong tea effectively restrain the chemiluminescence of luminol induced bysuper oxygen anion free radical. The strength of the chemiluminescence presents the descending trend with the increasing of theconcentration of green tea, black tea and wulong tea. A comparison of the antioxidation effects shows that the strength is in theorder of green tea, black tea and wulong tea.
