摘要
采用漫反射红外定量分析技术测定了诺氟沙星胶囊的含量,可排除辅料的影响,且吸光度与诺氟沙星的浓度呈良好的线性关系,平均回收率为98.23％,RSD为1.56％。方法简便、准确、可靠,可用于诺氟沙星胶囊的含量测定。
The norfloxacin (NFXC) content in capsules was determined by diffuse reflection FTIRS method, for the quality control of the drug. The interference of subsidiary materials in the drug was eliminated satisfactorily. Linear relationship between the concentration of norfloxacin and absorbance kept very well. Recovery test performed by standard addition method achieved an average value of 98. 23%, with RSD of 1. 56%.
