- W2363160261 abstract "Objective To establish a new HPLC method for determination the content of nifekalant hydrochloride and nifekalant hydrochloride injection and for the study of impurities. Method Nifekalant hydrochloride and nifekalant hydrochloride injection were determined by using C 8 column(250 mm×4.6 mm, 5μm) with UV detector at 270 nm. The mobile phase consisted of acetonitrile-0.02 mol·L -1K 2HPO 4-triethylamine(25∶27∶0∶5). Result The average recoveries of hydrochloride nifekalant injection were 99.67%, 99.75% and 99.80%,and the precision(RSD) were 0.88%, 0.80% and 0.69%, for three nifekalant hydrochloride concentrations, respectively. Conclusion The results showed that the method can be used for the analysis of hydrochloride nifekalant, and has the advantages of accuracy, fastness and convenience." @default.
