| Abstract: | Objective] To study the optimum ultrasonic extraction conditions of Lushan Yunwu Tea.Method] Effects of ultrasonic time,the ratio of material to liquid,the concentration of ethanol on extraction rate of tea polyphenols from Lushan Yunwu Tea were investigated.On the basis of single-factor test,orthogonal test L9 （33） was designed.Result] The optimal extraction conditions are as following：ethanol 70％,time 20 min,solid-liquid ratio 1 ∶ 6 g/ml.Under these conditions,the extraction rate of tea polyphenols is 14.35％.Conclusion] The study can provide reference basis for tea polyphenols extraction. |
