Abstract:
Objective:Studying changes of chemical constituents of Cinnamomum cassia after compatibility in Coptis chinensis;determining the amount of cinnamic acid in the decoction.Method:An YWG C18 column was used with a mobile phase of CH3CN-0.01%H3PO4(27∶73),the flow rate was 1.0 ml*min－1 and the detection wavelength was 280 nm.Result and Conclusion:The calibration curve of cinnamic acid had good linear relationship in the range of 0.112～4.48 μg.The average recovery was 100.0%, the relative standard deviation was 0.66%. The amount of cinnamic acid was decreased in the decoction, and the decreased degree was related with the ratio of C． chinensis to C． cassia.
