| Abstract: | In the paper, a facility method for the determination of tea polyphenols in cachou was studied. In the facility method, the best absorption wave length was 274 nm. The experiment obtained the recoveries range from 95. 1% to 102.2 % and the relative standard deviation was less than 0.29 %, quantity of tea polyphenols in cachou was 9.392 g/kg in the facility method. These results showed that the facility method was feasible, and it was a fast determination by the spectrophotometric method, and it was easy to operate. |
