Abstract:
OBJECTIVETo study, the high polar media-water extraction process of Herba epimedii with the microwave technology.
METHODThe single parameters of extraction process was investigated with dry extract yield and extraction efficiency of icariin as content index.
RESULTThrough studying the single parameter, the optimal conditions are as follows: 70% ethanol as wetting solvent, volume of solvent to weight of material equal to 6:1 in wetting, 30 min wetting time, 2.5 min microwave irradiation time, volume of solvent to weight of material equal to 50:1 in extraction process, 10 min microwave-assisted extraction time.
CONCLUSIONCompared with conventional methods, microwave-assisted extraction (MAE) after Microwave Pretreament (MP) of raw material was higher extraction efficiency and time-saving.
