Study on water extraction process of Herba epimedii with microwave technology / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study, the high polar media-water extraction process of Herba epimedii with the microwave technology.</p><p><b>METHOD</b>The single parameters of extraction process was investigated with dry extract yield and extraction efficiency of icariin as content index.</p><p><b>RESULT</b>Through studying the single parameter, the optimal conditions are as follows 70% ethanol as wetting solvent, volume of solvent to weight of material equal to 61 in wetting, 30 min wetting time, 2.5 min microwave irradiation time, volume of solvent to weight of material equal to 501 in extraction process, 10 min microwave-assisted extraction time.</p><p><b>CONCLUSION</b>Compared with conventional methods, microwave-assisted extraction (MAE) after Microwave Pretreament (MP) of raw material was higher extraction efficiency and time-saving.</p>
