Objective: To study comparatively the HPLC FPS of Chinese Red Ginseng and Korean Ginseng in the same group. Methods: The HPLC FPS of samples of Red Ginseng were established. Results: The chromatographic overlap rate of them was over 65%, even though the overlap rate of 3 samples of korean Ginseng was only 63%～66%. The relative area resultant of 8 samples was over 55%. Conclusion: The qualities of analyzed samples are similar and the HPLC FPS can provide the useful formation for the quality estimation of Radix Ginseng.
