Abstract: Objective To establish a RP-HPLC method for the determination of ephedrine hydrochloride in Huanglong Zhike granules. Methods Agilent Extend C18 column was used. The mobile phase was acetonitrile-0.1% phosphoric acid(0.1% triethyamine) (10:90). The detection wavelength was set at 207nm. Results A good linearity was obtained in the range of 0.0700μg to 1.400μg(r=1.0000). The average recovery was 98.7%. Conclusion This method is simple, accurate and reproducible, and can be used for the quality control.
