| Abstract: | Marinated method was applied for extracting green tea pigment in the black teas. The content of the green tea pigment was determined by specyrometric method, the optimum determined conditions were obtained by the tests. The recovery was 101.32% - 109.15% and the coefficient of variation was less than 0.28%. |
