ABSTRACT
OBJECTIVE:
To establish a method for the content determination of ephedrine hydrochloride in Luofu mountain rheumatism plaster.METHODS:
HPLC was performed on the column of Eclipse XDB-C18 with the mobile phase of acetoni-trile-0.1%phosphoric acid(9∶91,V/V),at the flow rate of 1.0 ml/min. The detection wavelength was 207 nm,the column tempera-ture was 40 ℃,and the volume was 5 μl.RESULTS:
The linear range of ephedrine hydrochloride was 81.6-408 ng(r=0.999 7);RSDs of precision,stability and repeatability tests were lower than 2%;and the average recovery rate was 96.73%(RSD=1.9%, n=6).CONCLUSIONS:
The method is fast and accurate,and can be used for the content determination of ephedrine hydrochlo-ride in Luofu mountain rheumatism plaster.
