Abstract:
Objective: To establish a simple and accurate method for Chuanxinlian Tablets (Herba Andrographis). Methods:The contents of dehydroandrographolide in Chuanxinlian Tablets was determined by FIA. The detection wavelength was at 540nm. Results:The linear was 0.2～1mg?mL -1 , the average recovery was 101.7%, RSD was 0.7% , respectively. The sampling frequency was 120 samples?h -1 . Conclusion:The method is simple, rapid and stable. It is suitable for the analysis of this preparation.
