ABSTRACT

<p><b>OBJECTIVE</b>To develop the preparation method of licorice juice as a processing excipient and to determine the proper proportion of licorice juice and fructus evodiae during process.</p><p><b>METHOD</b>Nine experiments were carried out through L9 (3(4)) orthogonal design. The wetting results were compared by using different proportion of licorice juice and fructus evodiae.</p><p><b>RESULT</b>The optimal preparation process was as follows the licorice roots were cutted into slices and 12 times of water was added. Then they were decocted for 1 h. The second and third decoction were also carried out by 12 times of water and 1 h. The proper proportion of licorice juice and fructus evodiae was 11.</p><p><b>CONCLUSION</b>The preparation process is scientific and suitable to prepare the processing excipient.</p>
