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.
Conclusion:
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.
