Abstract:
OBJECTIVETo optimize the ultrasonic extraction condition for flavonoids from Chrysanthemum morifolium.
METHODThe extraction rate of flavonoids optimized condition (ethanol concentration, ultrasonic time, solvent quantity and extraction times) was determined by orthogonal design. UV-Spectrophotometry was used for the determination.
RESULTThe order of factors to affect the flavonoid extraction was ethanol concentration > extraction times > solvent quantity > ultrasonic time.
CONCLUSIONThe optimum ultrasonic extractions were: A2 B2 C3 D3. Compared with traditional extraction, ultraction method can save time, be easy to operate, improve extraction rates and need no heating.
