Abstract: Objective To establish an HPLC method for determination of baicalin and cinnamic acid in Bianyan oral solution simultaneously. Methods The Agilent Eclipse XDB-C18(4.6 mm×150 mm, 5 μm)was used, the mobile phase consisted of ACN-2% acetic acid (23:77), the flow rate was 1.0 ml/min, the detection wavelength was at 280 nm, the column temperature was at room temperature, and the inject volume was 10 μl. Results A good linear correlation was observed within the range of 0.085 1~3.404 8 g for baicalin (r=0.999 9) and 0.020 3~0.811 2 g for cinnamic acid(r=0.999 9). The average recovery (n=6) was 101.68% with RSD 2.85% for baicalin and 101.46% with RSD 2.07% for cinnamic acid. Conclusion The method was rapid, simple and accurate, which could be used for the overall quality control of Bianyan oral solution.
