【摘要】 目的建立锡类缓释贴膜中靛蓝的含量测定方法。方法采用Diamonsil C18柱;流动相为甲醇-0.2%醋酸(68∶32);检测波长285 nm;结果靛蓝的线性范围为1.1~5.5μg,r=0.999 9;平均回收率为97.0%,RSD=1.01%。结论该含量测定方法准确、稳定,可用于锡类缓释贴膜的质量控制。 更多还原
【Abstract】 Objective To establish a method for the determination of indigotin in Xilei oral sustained-release mucoadhesive films.Methods The C18 column was used.The mobile phase was composed of methanol-0.2 %acetic acid solution(68∶32).The detection wavelength was 285 nm.Results The calibration curve of indigotin was linear in the range of 1.1~5.5μg(r=0.9999)with average recovery 97.0%(RSD=1.01 %).Conclusion The determination method is accurate,stable and can be used to control the quality of Xilei Oral Su... 更多还原
