Objective To optimize the extraction of total flavonoids from stems and leaves of Scutellaria by hot water immersion method. Methods The extracting time, temperature and ratio of water were chosen as influencing factors, and based on results of single factor experiments, the analytical levels of these 3 factors were established. Experimental scheme was designed by central composite of response surface methodology. Results Taking extraction ratio of flavonoids as response, a mathematics model was established. The opti-mum scheme of extraction technology for rein was obtained, including extraction temperature 89℃, extraction time 70 min, and material-water ratio 1:55 (mL/g). In addition, the interaction analysis between 2 factors was analyzed. Conclusion This research provided a certain theoretical instrument and application value for the extraction of flavonoids in Scutellaria baicalensis.
