Determination of Ephedrine Hydrochloride in Tianyi Zhike Syrup by HPLC

GAO Min(Putian Institute for Drug Control,Putian 351100,China)  
OBJECTIVE To establish a method for determination of Ephedrine Hydrochloride in Tianyi Zhike Syrup.METHODS Using a HPLC method with Angilent C_(18)(4.6mm×150mm;5μm)column,the mobile phase was methanol-0.025mol·L~(-1) potassium dihydrogen phosphate solution(pH adjusted to 3.0 by phosphoric acid)(12:88),the detection wavelength at 206nm,flow rate was 1.0ml·min~(-1),and the injection volume was 10μL.RESULTS The standard curve of Ephedrine Hydrochloride was rectilinear within the range of 0.1064μg~0.9576μg,r=0.9999.The average recoveries was 100.2%,RSD=0.96%.CONCLUSION The method was accurate 、simple and rapid,it can be used for the method of determination.
