Abstract:
AIM: To establish a quantitative analytical method of ferulic acid in Kexintong Dripping Pills (Moschus, Rhizoma Chuaxiong, Rhizoma Corydalis, etc.) based on the capillary zone electrophoresis. METHODS: P-Nitrobenzoic acid was adopted as the internal substauce with a 30 mmol?L -1 borax solution at equal electrophoresis current of 50 ?A, detection wavelength at 295 nm, uncoated fused silica capillary of 75 ?m?50 cm, temperature at 20 ℃. Sample was injected for 5 s at pressure of 20PSI. RESULTS: Good linearity was showed in the concentration range of 4～264 mg?L -1 , RSD was 1.71%(n=6), and the recovery was 100.47%?2.1%. CONCLUSION: The result indicates the proposed method is convenient, rapid, accurate and reliable, it is a proper method for the quantitative analysis of ferulic acid in Kexintong Dripping Pills.
