Abstract: The optimum ultrasonic extraction technology of gardenia yellow was obtained, and the mathematical model of correlation among temperature, time, ratio of material to liquid and concentration of solvent was established by means of quadratic general rotary unitized design. The results indicated that the optimum extraction conditions are as follows: ratio between gardenia and solvent 1:13, extraction time 35 min, extraction temperature 50 ℃ and concentration of solvent 70%. Through Data Processing System, the mathematics model was set up. Under the above conditions, the absorbance of gardenia yellow is 0.994.
