OBJECTIVE To optimize the extraction technology of flavonoids from Emilia sonchifolia( Linn.) DC with surfactant-ultrasound extraction.METHODS Orthogonal test were used to study the extraction conditions with the extracting rate of flavonoids as indexes.RESULTS The optimal technical conditions as follows:1.0%tween-80 as solubilizing agent ,70%ethanol as extracting solvent ,the proportion of raw material to solvent was 1∶15,the ultra-sound treatment time was 60 min.Under this conditions , the extraction rate reached 4.63%, which obviously higher than the conventional extraction methods.CONCLUSION The surfactant-ultrasound method is higher extraction rate,lower costs and can be applied multipurposely.
