ABSTRACT
[Objective] To establish a method for the determination of ferulic acid and salvianolic acid B contents in Yixin Tablets. [Methods] High pressure liquid chromatography (HPLC) was adopted. The chromatographic conditions were 100-fold methanol as solvent, Bonification for 30min, gradient elution on C18 comlumn with acetonitrile and phosphoric acid as mobile phase, the detection wavelength being 320nm. [Results] Ferulic acid had a good linearity in the range of 0.024 32 - 0.729 60 ?g and r=0.999 9; salvianolic acid B had a good linearity in the range of 0.416 8-12.504 0?g and r = 0.9999; the average recovery rate was 100.95% in ferulic acid and 99.35% in salvianolic acid B respectively. [Conclusion] This method is simple, accurate and with good reproducibility.
