To set up the method to control the quality of Dingxiang-Shidi Tablet.Method:TLC was used to identify ginsenoside and gallic acid.HPLC was used on a Shimazu LC-10ATVP to detect the content of eugenol;the chromatographic system consisted of octadecyl silane chemically bonded silica

methanol-water（65:40） as mobile phase.The detecting wavelength was at 280 nm.The number of theoretical plates calculated by eugenol should be no less than 3000.Result:The spots of test substance and reference substance in the chromatogram were the same.The flowing out time of peak of all the components was appropriate with good separation effect.The peak area and theoretical plates were in a high level.All of them can assure the authenticity

accuracy and repeatability of the testing results.The negative results won’t interfere the results.This method was strongly specific.Conclusion:This method can be used to control the quality of Dingxiang-Shidi Tablet.
