ABSTRACT
AIM:
To establish a determination for ephedrine hydrochloride and pseudoephedrine hydrochloride in Suxing Capsules(Herba Ephedrae, Semen Armeniacae Amarum, Fructus Perillal, etc.).METHODS:
HPLC with Agilent ZORBAX Extend C_(18) (250 mm?4.6 mm, 5 ?m) column was used. Acetonitrile-0.2% H_3PO_4(5∶95) was used as a mobile phase. The flow rate was 1.0 mL?min~(-1). The detection wawelength was at 210 nm.RESULTS:
The methodological evaluation showed that this method had a good repeatability and reproducibility; The average recovery of ephedrine hydrochloride was 99.65% and RSD was 1.6%. The average recovery of (pseudoephedr)ine hydrochloride was 98.90% and RSD was 2.3%.CONCLUSION:
This method is simple, quick, accurate and with good reproducibility and can be used for the quality control of Suxing Capsules.
