【摘要】 目的测定缩宫素的含量。方法采用高效
液相色谱梯度洗脱法,选用Diamonsil C18柱,以15.6 g/mL磷酸二氢钠溶液及乙腈-水(1:1)为流动相梯度洗脱,检测波长为220 nm。结果线性范围为0.5~100 IU/mL。平均加样回收率为96.9%。结论高效
液相色谱法所用方法准确、简便。 更多还原
【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
