| Abstract: | Based on single factor tests involving the yield of total flavonoids as an evaluation index,orthogonal tests were conducted at L9（34） level to investigate the effect of surfactant sodium dodecyl benzene sulfonate（SDBS） on the yield of flavonoids extracted from sophora japonica by supercritical CO2.The optimal technology for extracting flavonoids from sophora japonica was established.Results show that adding SDBS helps to increase the extraction rate of the total flavonoids from sophora japonica by about 93.7%.In terms of the optimal process for extracting the flavonoids,it involves an extraction temperature of 50 ℃,extraction pressure of 35 MPa,a SDBS dosage of 2%（mass fraction）,and an ethanol volume ratio of 75%. |
