Study on ultrasonic extraction techniques of flavonoids in Chrysanthemum morifolium / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To optimize the ultrasonic extraction condition for flavonoids from Chrysanthemum morifolium.</p><p><b>METHOD</b>The 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.</p><p><b>RESULT</b>The order of factors to affect the flavonoid extraction was ethanol concentration > extraction times > solvent quantity > ultrasonic time.</p><p><b>CONCLUSION</b>The 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.</p>
