Abstract
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.
Conclusion:
Chitosan clarification method can replace alcohol-precipitation method in refining of the decoction of Jiangtangtongmai.
