Abstract:
Objective To establish a RP- HPLC method for the determinatio n of protocatechualdehyde in Danqi tablet. Methods LiChrospher RP- 18 column w as used, the mobile phase was MeOH- 1.5 % Hac(1∶ 9) with a flow rate of 1.0 mL/ min, and the detection wavelength was at 280nm. Results There was a goo d linearity within the range of 0.030～ 0.150 ? g of protocatechualdehyde. The average recovery was 103.08 % and RSD was 0.796 % (n=5). Conclusion This method can be used for the quality control of Danqi tablet .
