摘　　要：目的制订青黛软膏的质量标准。方法用薄层色谱法与硝酸反应法对青黛软膏进行定性鉴别,用紫外分光光度法测定青黛软膏中靛蓝的含量,测定波长为(609±1)nm。结果靛蓝的线性范围为1.0～6.0μg/L,r=1.0;平均回收率为99.4%,RSD为0.38%。结论该方法简便、快速、准确,专属性强,可用于青黛软膏的质量标准。Objective To establish the quality standard of indigo ointment, Methods The indigo ointment was identified by TLC and nitric acid reaction. The content of indigotin was determined by ultraviolet spectrophotomety at （609 ± 1）nm wavelength. Results The linear range of indigotin was 1.0 - 6.0μg/mL, r = 1.0. The average recovery rate for indigotin was 99.4%, RSD = 0. 379 4%, Conclusion The method is simple, rapid, accurate and specific, It can be used for the quality control of indigo ointment.
