| Abstract: | A method for determination of related substances in amoxicillin sodium and clavulanate potassium was established.Kromasil C18 column was used,mobile phase A was 0.01 mol/L potassium dihydrogen phosphate(adjusting pH to 6.0 with 2 mol/L sodium hydroxide),mobile phase B was 0.01 mol/L potassium dihydrogen phosphate(adjusting pH to 6.0 with 2 mol/L sodium hydroxide)-acetontrile(20︰80),detection wavelength was 230 nm.The flow rate was 1.0 mL/min.The limit of quantitation was 0.8 ng,the minimum detection limit was 0.24 ng.The separation degrees of various destructive effect samples were greater than 1.5,it was up to the specification.The method is rapid,accurate,high sensitivity and strong specificity,can meet the need for determination of related substances in amoxicillin sodium and clavulanate potassium. |
