Abstract
Objective To establish an HPLC method for determination of ephedrine hydrochloride and pseudoephedrine hydrochloride in Maxing oral solution. Methods Phenomenex Hydro-RP (250 mm×4.6 mm, 4 μm) was adopted. Acetonitnile (A) and 0.1% phosphonic acid solution (0.1% triethanolamine solution)(B) was used as gradient mobile phase(0-20 min, 3%→10% A)at flow rate was 1.0 ml/min and the program of UV gradient absorbance detection was 210 nm. The sample volume was 20 μl. Results A good linearity was obtained over the concentration range of 0.99-39.6 μg/ml for ephedrine hydrochloride (r=0.999 9) and 1.09-43.6 μg/ml for pseudoephedrine hydrochloride (r=0.999 9). The average recovery of ephedrine hydrochloride was 101.5% with RSD of 1.77% (n=6), and the average recovery of pseudoephedrine hydrochloride was 100.8% with RSD of 1.96% (n=6). Conclusion This method was simple,accurate and quick,which could be used for determination and quality control of Maxing oral solution with good selectivity and repeatability.
