of purity of Ropinirole in presence of its impurities and forced degradation products. The method was developed using Waters Aquity BEH 100 mm, 2.1 mm, 1.7 μm C‐8 column with mobile phase containing a gradient mixture of solvent A and B. The eluted compounds were monitored at 250 nm. The run time was within 4.5 min which Ropinirole and its four impurities were well separated. Ropinirole was subjected
开发了一种新颖的稳定性指示梯度反相超高效液相色谱(RPUPLC)方法,用于测定存在杂质和强制降解产物的罗匹尼罗的纯度。该方法是使用Waters Aquity BEH 100 mm,2.1 mm,1.7μmC-8色谱柱开发的,流动相中含有溶剂A和B的梯度混合物。在250 nm处监测洗脱的化合物。运行时间在4.5分钟内,其中Ropinirole及其四种杂质被很好地分离了。罗匹尼罗经受了氧化,酸,碱,水解,热和光解降解的应力条件。发现罗匹尼罗在氧化和碱性胁迫条件下会显着降解,在酸,水,水解和光解条件下稳定。从主峰及其杂质中可以很好地分离降解产物,从而证明了该方法的稳定性,表明了该方法的有效性。所开发的方法已根据国际协调会议(ICH)指南在特异性,线性,检测限,定量限,准确性,精密度和鲁棒性方面得到验证。该方法也适用于测定药物剂型中的罗匹尼罗和溶出度研究。
