【Abstract】 Objective To establish a HPLC method for assaying of oxitocin.Methods The gradient elution was used with Diamonsil C18 column and UV detection at 220 nm.The mobile phase was 15.6g/mL sodium dihydrogen phosphate buffer and acetonitrile-water(1:1). Results The oxitocin curves were linear between 0.5-100 IU/mL(r=1.0000),and the recovery rate of the standards added was 96.9%. Condusion The method is accurate,simple. 更多还原 【关键词】 高效液相色谱法; 缩宫素; 含量测定; 【Key words】 HPLC; oxitocin; content determination;
