[Preparation of licorice juice as a processing excipient].
OBJECTIVE
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.


METHODS
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.


RESULTS
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 1:1.


CONCLUSIONS
The preparation process is scientific and suitable to prepare the processing excipient.
