Study on extraction technology for extract and flavonoids in Chrysanthemum morifolium by orthogonal design / 中国中药杂志

ABSTRACT

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