Abstract:
OBJECTIVE:To optimize the extraction and preparation technics of icariin by orthogonal design.METHODS:The icariin was extracted by the ethanol reflux and the ethanol ultrasonic extracting process respectively;the quantity and concentration of ethanol,extracting time and extracting times were investigated with the content of the icariin as a indicator.RESULTS & CONCLUSION:The ethanol refluxing process is better than the ethanol ultrasonic process in the extraction of icariin.The most optimistic condition of extracting of icariin in ethanol refluxing extracting process was as follows:the crude drug was extracted for 3 times(40min/time)by using 60% ethanol,which is 8 times of the amount of the crude drug.
