| Abstract: |
| OBJECTIVE To establish an HPLC method for the determination of cinobufagin and recibufogenin in Tongqiao Yixin pill. METHODS The analysis was performed on a SinoChrom ODS2 column. The mobile phase consisted of 0.5% potassium phosphate（pH 3.2）acetonitrile (52∶48), and the flow rate was 1.0 mL·min-1. The detection wavelength was 296 nm. RESULTS The average recovery and RSD were 99.77% and 0.49% for cinobufagin, 99.39% and 0.60% for recibufogenin, respectively. CONCLUSION This method is simple and reliable for the quality control of Tongqiao Yixin pills. |
