Abstract:
AIM:To set up a method of simultaneously determining the contents of ephedrine and pseudoephedrine in Zhisou Lixiao Oral Liquid (Herba Ephedrae, Radix et Rhizoma Glycyrrhizae, Semen Raphani, etc). METHOD: The HPLC-quantitative analysis was carried out on a column of Sinochrom ODS-BP by using a mobile phase of acetonitrile-0.02 mol/L potassium dihydrogen phosphate (pH=2.7), (4∶100, with 0.1% triethylamine) under a flow rate of 1.5 mL/min. 207 nm was selected as the wavelength of detector. RESULTS: The linear range of ephedrine was 20.8-208.0 ?g/mL(r=0.999 7) and pseudoephedrine's was 15.0-150.0 ?g/mL(r=0.999 8). The recoveries of them were all between 95% and 105%(RSD
