摘要
采用荧光光谱扫描法定性定量研究了6种花茶对羟自由基(·OH)诱导的DNA氧化损伤的保护作用.结果表明:桂花茶、复合花茶、绿茶和芍药花茶的保护作用要优于红玫瑰花茶和金莲花茶,且各花茶的保护作用在0～1 mg/mL范围内均随质量浓度的增加而增强.该方法的稳定性和重复性都较好.
The protection functions of six types of flower tea on ·OH-induced DNA damage were researched qualitatively and quantitatively through fluorescent spectrum scanning.Result showed that the protection functions of osmanthus fragrans tea,mixed flower tea,green tea and paenoia albiflora tea are better than that of rosa rugosa（red） and tropaeolum majus tea,and the protection functions of six types of flower tea are all enhanced with the improvement of concentration（0～1 mg/mL）.The stability and repeat of fluorescent spectrum scanning are both good.
