| Abstract: | The leaching effect of tea polyphenols in Yiyang Black Tea was investgated under different conditionds. The content of tea polyphenols in Yiyang Black Tea was determined by visible spectrophotometry and atomic absorption spectrometry respectively. The results of two methods showed that the relateve coefficient was satisfactory. The two methods have their advantages, such as simple, rapid, high accuracy and good reproducibility and can be applied to detect the tea polyphenols in tea. |
