Abstract

Objective To establish a method for the determination of gallic acid in Jingtiansanqi capsules.Methods HPLC was used.The determination was performed on a Diamonsil C18(200 mm×4.6 mm,5 μm)column by UV detector at 271 nm with methanol-0.6% Phosphoric acid(12∶88) as the mobile phase.The flow rate was 1.0 mL/min with column temperature of 40 ℃.Results The calibration curve showed a good linearity within the range of 160.1～800.5 ng(r=0.999 9).The average recovery was 99.05% with RSD of 0.88%(n=6).Conclusion The method is simple,rapid and accurate.
