[Comparison of cinnamic acid contents in Rhizoma Typhonii before and after being processed].
OBJECTIVE
To compare the diversity of contents of Cinnamic acid in Rhizoma Typhonii before and after being processed.


METHODS
RP-HPLC.


RESULTS
There were great difference of the contents of Cinnamic acid in various batch. The contents degraded after had been processed.


CONCLUSIONS
Cinnamic acid in Rhizoma Typhonii can be separated completely under the condition of RP-HPLC. Precision and reproduction of the method is preferable. The method is simple, convenient, reliability and can be as a kind of method to determine the contents for Rhizoma Typhonii.
