Abstract: 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。
