ABSTRACT
Object To establish a new method to determine protocatechualdehyde in Maodongqing Sustained- release Tablet. Methods The RP- HPLC method was applied with CH3OH and 1 % acetic acid as mobile phase, flowrate at 1.0 mL/min, and detection wavelength at 312 nm. Results In the range from 11.7 ng to 140.4 ng, protocatechualdehyde was in a good line with peak area, r=0.99995, the average recovery ratio was 96.41 % , RSD=1.04 % (n=5). Conclusions It was the first time to establish the RP- HPLC method to determine and control the protocatechualdehyde in Maodongqing Sustained- release Tablet with accuracy and a good reproducibility.
