ABSTRACT
Objective To establish the method for detemining the content of ephedrine hydrochloride in Zhike Pingchuan Tangjiang by HPLC. Methods Diamonsil ODS1 C_(18) Column was used with acetonitrile -0.1% phosphoric solution (with 0.1% triehylamine) (3 97) as the mobile phase, the detection wavelength as 205 nm, and flow rate was 1.0 mL/min. Results The calibration curve was linear at the range of 0.12~ 0.96 ?g for ephedrine hydrochloride and linear equation was Y= 109759X+3792.8, r=0.9998. The average recovery was 98.4% and RSD was 0.87% (n =5). Conclusion This method was simple, accurate and proper, with good reproducibility. It can be used for quantitative analysis of ephedrine hydrochloride in Zhike Pingchuan Tangjiang.
