- W2379281013 abstract "OBJECTIVE To establish a RP-HPLC method for the determination of related substance and content in metaraminol bitartrate and its injection.METHODS Using a Phenomenex Gemini C18 column(4.6 mm×250 mm,5 μm).The mobile phase consisted methanol-0.03% sodium hexanesul fonate(adjust the pH value to 3.0 with 40% phosphoric acid solution)(20∶80).The detection wavelength of related substance was 220 nm,The detection wavelength of content was 272 nm.The column temperature was 35 ℃.Inject volume was 20 μL.RESULTS The low detection limit for the related substance of metaraminol bitartrate was 0.6 ng,the quantitative limit for the content of metaraminol mitartrate was 7.6 ng.The linear range for the content of metaraminol bitartrate was 12.5-75.0 μg· mL-1,r=0.999 9.The recoveries of metaraminol bitartrate injection were 100.5%,100.8%,101.2%,and its RSD was 0.5%(n=9).CONCLUSION The method is simple,rapid,accurate and is suitable for the determination of the metaraminol bitartrateans its related substanceds" @default.
