| Abstract: | Objective To study the water extracting technology of tea polyphenol in puer raw tea by means of orthogonal test L9（3^4）. Methods The tea polyphenol in puer raw tea was Determined by spectrophotometry. Results The results showed the optimum extraction process was as follows：extraction temperature 80 ℃, ratio of material to liquid 1：30 and extraction time 30 min. The average content of tea polyphenol in large-leaf puer raw tea from Mengku in yunnan province was （16.30 ± 0.63 ） mg/g under this condition. Conclusion It is feasible and simple to extract tea polyphenol from puer raw tea by water extracting technology. |
