| Abstract: | The research took Rhododendron pulchrum Sweet. Flowers as raw material and selected the ethanol concentration, liquid-solid ratio, and extraction time and extraction temperature as the key factors with flavonoids concentration as the evaluation index. Through single factor experiment and U12 （64） uniform design experiment, the optimization of flavonoids extraction technique from Rhododendron pulchrum Sweet. Flowers were determined. The result showed that the optimal conditions of extraction were obtained as follows;50 % of ethanol concentration, liquid-solid ratio of 120 mL.g-1, 60 min of extraction time, 60 ℃ of extraction temperature. |
