Abstract:Objective: To establish an HPLC method for the determination the content of ethylenediamine diaceturate injection. Method: The Mhima AQ (200 mm ×4. 6 mm,5 μm) column was used,the mobile phase consisted of water-phosphoric acicl-triethyl- amine solution (100: 0. 15: 0. 2) ,the flow rate was 1.0 ml-min-1 ,the detection wavelength was 225 nm. Result: The linear range of eth- ylenediamine diaceturate was 0. 25-2. 04 μg (r =0. 999 8) ,the average recoveries (n =9) was 98.6% (RSD O. 85% ). Conclusion: The method is simple, accurate and repeatable,it can be used for the determination the content of ethylenediamine diaeeturate injection.
