ABSTRACT
Objective To establish method for simultaneous determination of hesperidin, cinnamaldehyde and eugenol in Chunyang Zhengqi capsules by high performance liquid chromatography. Methods The column was Agilent PorosheⅡ 120 EC-C18 (4.6 mm×150 mm, 4 μm). The mobile phase was acetonitrile-water with gradient elution. The column temperature was 35℃. The flow rate was 1.0 ml/min, and the detection wavelength was 284 nm. Results The methodological verification showed that hesperidin, cinnamaldehyde and eugenol had a good linearity (r≥0.999 9). The precisions were less than 2.0%. The average recovery was between 98.0% and 101.9%. The stability and repeatability of RSD were also less than 3.0%, which met the requirements of method validation. Conclusion The method is simple, stable, reproducible and accurate, which could be used to the quality control of Chunyang Zhengqi capsules.
