Determination of ketoconazole in compound ketoconazole ointment by secord derivative spectrophotometry
-
摘要: 本文采用二阶导数分光光度法直接测定酮康唑的含量。实验结果表明:本法简便、正确、重现性好。在16~48μ/ml浓度范围内线性良好。r=0.9994,RSD=0.65%。Abstract: The paper reports the direct determination of ketoconazole in compound ketoconazole cintment by second derivative spectrophotometry.The result shows that this method is simple, aceurate and reproducible.The calibration curve is linear in the range of 16 to 48μg/ml, r =0.9994, RSD = 0.65%.
