[Study on extraction technology for extract and flavonoids in Chrysanthemum morifolium by orthogonal design].
OBJECTIVE
To ascertain extraction technology condition for extract and flavonoids from Chrysanthum morifoliwn.


METHODS
The optimizing ultrasonic extraction condition on the basis of extractive yield and flavonoids were determined by orthogonal design.


RESULTS
The order of factors which affected the flavonoid extraction was extraction times > ethanol concentration > ultrasonic time > solvent quantity.


CONCLUSIONS
The optimum ultrasonic extractions are A2B3C3D3. Compared with traditional extraction, ultraction method is timesaving, simple to operate, stable and need not be heated.
