Abstract: The content of cyanidin of the ancient tea tree superior lines was analyzed by high performance liquid chromatography (HPLC). The results showed that the optimal mobile phase of HPLC analysis on the content of cyanidin of the ancient tea superior lines consisted of acetonitrile and ultrapure water (9:1, V/V). Compared with the control Fuding Dabaicha, line 4 of ancient tea tree had the highest content of cyanidin and line 2 had the lowest content of cyanidin, which both showed the significant difference from the control.

Key words: high performance liquid chromatography (HPLC), ancient tea tree, cyanidin
