OBJECTIVE: To ascertain extraction technology condition for extract and flavonoids from Chrysanthum morifoliwn. METHOD: The optimizing ultrasonic extraction condition on the basis of extractive yield and flavonoids were determined by orthogonal design. RESULT: The order of factors which affected the flavonoid extraction was extraction times > ethanol concentration > ultrasonic time > solvent quantity. CONCLUSION: The optimum ultrasonic extractions are A2B3C3D3. Compared with traditional extraction, ultraction method is timesaving, simple to operate, stable and need not be heated.
