[Application of membrane separation technology in extraction process of Chuanxiong Chatiao granules].
OBJECTIVE
To apply the membrane separation process in the concentration process of Chuanxiong Chatiao granules and to lay the foundation for its industrialized application.


METHODS
The type of membrane, the optimal pressure, the optimal temperature and the optimal detergent were selected by the single factor method. A comparative study was conducted between qualities of extracts from Chuanxiong Chatiao granules by new and traditional processes.


RESULTS
The type of membrane was determined to be SMN-130A2350054. The optimal pressure was 1.7 MPa. The optimal temperature was 36 degrees C and the optimal detergent was 1% sodium polyphosphate. The qualities of extracts from Chuanxiong Chatiao granules by new and traditional processes showed no difference.


CONCLUSIONS
The selected membrane separation process can effectively achieve concentration and save energy. The extracts from Chuanxiong Chatiao granules by the new process show no difference with traditional processes. Therefore, it provides basis for the industrialized application of Chuanxiong Chatiao granules.
