  • Received Date: 2009-12-28
  • Rev Recd Date: 2010-03-09
  • Objective To set up a method of simultaneously determining the contents of ephedrine and pseudoephedrine in Xuanfei Qingre mixture(Herba Ephedrae,Semen Armeniacae amarum,Bulbus Fritillaria thunbergii,Radix scutellaria,etc). Methods The HPLC-quantitative analysis was carried out on a column of Agilent ZORBA× SB-CC18 by using a mobile phase of acetonitrile-0.02 mol/L potassium dihydrogen phosphate(adjusted with phosphoric acid pH=2.7),(4100,with 0.1% triethylamine)under a flow rate of 1.2 ml/min.207 nm was selected as the wavelength of detector. Results The linear range of ephedrine was 11.04~222.8 μg/ml(r=0.999 9)and pseudoephedrine's was 8.27~165.4 μg/ml(r=0.999 9).The recoveries of them were all between 95% and 105%(RSD<3%). Conclusion This method is simple,reproducible and specific.

Abstract: Objective To set up a method of simultaneously determining the contents of ephedrine and pseudoephedrine in Xuanfei Qingre mixture(Herba Ephedrae,Semen Armeniacae amarum,Bulbus Fritillaria thunbergii,Radix scutellaria,etc). Methods The HPLC-quantitative analysis was carried out on a column of Agilent ZORBA× SB-CC18 by using a mobile phase of acetonitrile-0.02 mol/L potassium dihydrogen phosphate(adjusted with phosphoric acid pH=2.7),(4100,with 0.1% triethylamine)under a flow rate of 1.2 ml/min.207 nm was selected as the wavelength of detector. Results The linear range of ephedrine was 11.04~222.8 μg/ml(r=0.999 9)and pseudoephedrine's was 8.27~165.4 μg/ml(r=0.999 9).The recoveries of them were all between 95% and 105%(RSD<3%).
