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.
