尼索地平(Nisoldipine)固体及其无水乙醇溶液经不同光源照射后,用紫外分光光度法测定光照样品中尼索地平残余量浓度。试验结果表明:本品固体对光较溶液稳定。薄层层析表明光照样品显示杂质斑点。试验结果对本品生产、制剂、贮藏具有一定的实际意义。 Nisoldipine solid and its absolute ethanol solution were irradiated by different light sources, and the residual concentration of nisoldipine in the irradiated samples was measured by UV spectrophotometry. Test results show that: This solid light on the solution to the light stability. Thin layer chromatography showed that light samples showed impurity spots. The test results on the production of this product, preparation, storage has a certain practical significance.
