Determination of ferulic acid in Jianpibuxue tablets by HPLC / 西安交通大学学报(医学版)

ABSTRACT

Objective To establish a determination method of ferulic acid in Jianpibuxue tablets.(Methods)HPLC was used with Lichrospher C_(18)(4.6mm?250mm,5?m) as the column.The mobile phase was a mixture of acetonitrile-0.378mol/L acetum(30∶70) and in a flow rate of 0.8mL/min;The detective wavelength was 321nm;Column temperature was room temperature and the injection quantity was 10?L.(Results)Ferulic acid in samples was well separated.The linear range was 1.0-10.0mg/L(r=0.9996).The average recovery was 99.8% and RSD was 0.26 %(n=6).Conclusion This method can be used for quality control of ferulic acid in Jianpibuxue tablets.
