Objective To establish a RP-HPLC method for the content determination of chorogenic acid in Jinsang Oral Liq-uid. Methods The determination was performed on the Ultimate ODS C18 column(250 mm × 4. 6 mm,5 μm) with the mobile phase of acetonitrile-0. 5% phosphoric acid(26 :74)at the flow rate of 1. 0 mL/min. The detection wavelength was set at 328 nm and the injection volume was 10 μL. Results The linear range of chorogenic acid was 0. 010 5-1. 260 μg/mL( r=0. 999 8) with an average recovery rate of 98. 08% RSD=0. 73% ( n=6). Conclusion The method is simple,accurate and strongly specific with good repro-ducibility and can be used for the content determination of chorogenic acid in Jinsang Oral Liquid.
