Objective: To establish a reversed-phase high performance liquid chromatography method for the determination of emodin content in Gongkangshu. Methods: A Shimdze CLCODS column was used. The mobile phase was methanol-water phosphoric acid (80∶2 0∶0 5 ). The detection wavelength was 286nm and the flow rate was 1ml·min 1 . . Results: The average recovery rate was 99 11% (RSD =0 98%). Conclusion: The method is simple, accurate and reproducible.
