摘要
目的 建立紫外分光光度法测定塞曲司特片的溶出度。方法 于400~200nm波长处扫描,确定塞曲司特在266nm处有最大吸收。结果 塞曲司特浓度与吸光度值A呈良好的线性关系,线性范围4-20μg·mL^-1(r=0.9994),平均回收率为100.2%,RSD为0.45%(n=3)。结论 该方法测定塞曲司特片溶出度,结果准确,重现性好。
OBJECTIVE To establish an UV spectrophotography method for dissolution determination of Seratrodast tablets. METHODS To scan in the wavelength range of 400-200nm,and make sure Seratrodast had the largest absorption at wave length of 266nm. RESULTS The absorption was linear in the concentration range of 4-20μg·mL^-1 ( r =0. 9994). The average recovery was 99. 9%, RSD = 0. 45% ( n = 3). CONCLUSION The method was good,accurate and reproducible.
