研究了茶多酚在不同浓度,不同pH值,不同金属离子(Fe2+,Cu2+,Zn2+)存在下的化学发光,结果表明,茶多酚浓度对其发光强度有一定影响;pH越高茶多酚的发光强度越大;Cu2+可抑制茶多酚的发光,而Fe2+在一定条件下促进发光, Zn2+对茶多酚的化学发光没有影响。
The chemiluminescence of tea polyphenols was investigated under different concentrations, different pH value , and in the presence of different metal ions(Cu2+、Zn2+ or Fe2+) .Results showed that concentrations of tea polyphenols could not obviously affect their chemiluminescence intensity and the higher the pH value,the more the chemiluminescence intensity of tea polyphenols was; Cu2+ suppressed the photoactivities of tea polyphenols,but Fe2+ promoted it,and Zn2+ had no effects on their chemiluminescence。
