[Study on chitosan clarification refining the decoction of jiangtangtongmai by homogenous design method].
OBJECTIVE
To study the effect of chitosan clarification refining the decoction of Jiangtangtongmai by homogenous design method.


METHODS
The content of catalpol in the refined decoction by the alcohol-precipitation method and chitosan clarification method was determined by RP-HPLC.


RESULTS
Catalpol can be well preserved by chitosan clarification method.


CONCLUSIONS
Chitosan clarification method can replace alcohol-precipitation method in refining of the decoction of Jiangtangtongmai.
