Abstract:
OBJECTIVE:To establish a method for simultaneous determination of ephedrine hydrochloride,nitrofural and di-phenhydramine hydrochloride in Compound diphenhydramine nasal drop. METHODS:RP-HPLC method was adopted. The determi-nation was performed on Inertsil ODS-3 C18 column with mobile phase consisted of 0.05 mol/L potassium dihydrogen phosphate buf-fer(pH 7.0)-acetonitrile(gradient elution)with flow rate of 1.0 mL/min. The detection wavelength was set at 256 nm,and the col-umn temperature was 35 ℃. The sample size was 20 μL. RESULTS:The concentrations of phedrine hydrochloride,nitrofural and diphenhydramine hydrochloride ranged 122.1-366.3 μg/mL(r=0.9999),5.2-15.5 μg/mL(r=0.9998)and 31.5-94.5 μg/mL(r=0.9994),respectively. The limits of quantitation were 2.442,0.010,2.520 μg/mL,and the limits of detection were 0.810,0.003, 0.830 μg/mL,respectively. RSDs of precision,stability and reproducibility tests were lower than 1.0%. The recoveries of them were 99.2%-101.7%(RSD=0.9%,n=9),96.4%-102.0%%(RSD=1.7%,n=9),100.2%-101.9%(RSD=0.4%,n=9),respec-tively. CONCLUSIONS:The method is simple,accurate and reproducible,and can be used for simultaneous determination of ephedrine hydrochloride,nitrofural and diphenhydramine hydrochloride in Compound diphenhydramine nasal drop.
