Abstract：To preferred the optimum extraction technology from the Sophora japonica L. Took the extraction rate of total flavonoids contained in Sophora japonica L as the evaluation index. Using L9(34) orthogonal design experiment, 3 factors such as medicinal material grinding degree, kind of alkali, extraction times were screened for Sophora japonica L extraction optimum process. Considered all kinds of factors, the optimal extraction conditions of the Sophora japonica L is C1B3A1, that is the Sophora japonica L is crushed into coarse powder, adjusting pH with lime water, extracting 3 times. This method provides a basis for improvement of extraction of total flavonoids from Sophora japonica L rate.
